Cubase 11.0.40 HiDPI issues

My troubles with not drawing the VST windows right were the most strange in HiDPI mode. For some VST windows the outside frame of the window was correctly dwawn in the place I last saved my project but the inside of the frame was drawn in the left-corner of the screen.

And with the plugin called “Transfuser-2” from Air Music Technology the edit window of the plugin is never drawn both in HiDPI mode as well in normal mode. I must close the GUI of that plugin to make Cubase draw it right.

The other DAWs that I use that do not have this problem with the GUI’s of the VSTs in both HiDPI mode as well in normal mode are:
“LIVE 11” by Ableton
“Waveform 11” by Tracktion
“Cakewalk by Bandlab” / former called SONAR
“Reason” from propellerhead (latest edition)

Also I do notice that at certain times some VST’s GUI’s are redrawn by Cubase creating first a white window on the place where a plugin is located and then draws the VST GUI again. It results when playing or recording that I see at those time a flickering white on the screen because of the redrawing. Also in the other mentioned DAW’s I do not have this problem.

We are going to try to allocate time to investigate this issue. Stay tuned.


Our tester took the time to test Transfuser-2 on several DAWs.

We can confirm that sometimes the GUI isn’t drawn on the bottom half. To me, this is back to the problem I already mentioned during my first post. This is likely due to an issue with OpenGL and Air Music Technology should fix it, and ideally consider porting to VST3 which fully encompasses the HiDPI workflow. Let us know how we could assist here.

Additionally, here is a brief overview of some of the competitors mentioned. With Tracktion we experimented bigger problems with this plugin, and much more with other plugins. Are you aware of a settings we’re not aware of? The plugin is small and layouts are broken:

Ableton Live 11 does not seem to be HiDPI-Aware. The main application just uses internal rescaling but the application is not HiDPI-Aware. The Plugins that we opened so far on Ableton Live were all blurry and their windows were HiDPI-Unaware. For instance here Fabfilter. Left is Ableton Live and Right is Cubase. Are you aware of an option that we aren’t aware of eventually?

Overall, Transfuser-2 seems very unstable on several DAWs. We recommend once again that you directly get in touch with them.


Hi Armand,
Thanks for getting back to me on the Transfuser-2 subject. I will pass the problem also to Air Music. With the Transfuser-2 software I have no problems when using it (after an closing and opening it again of it in Cubase).

I do think that building the screens and display the screens however in Cubase is different then the ones used by other DAWs. When using Cubase, at random intervals, I see that open VST windows are redrawn by Cubase resulting in first a white BOX (the flickering I see) of the open VST screens and then the VST image is drawn again. This happens with all of my VST’s that I have including the Steinberg build-in VST’s.

Also Cubase is the only DAW that hides all open VST windows when navigating elsewhere out of any Cubase windows. I wish there was a setting there to turn this behaviour off and maybe it is also related to that redrawing of VST windows at random intervals.

So I am still not happy about the fact that Cubase is not conistent with normal window behaviour and that when drawing a VST it doesn’t take the time long enough to fully drawn the GUI of a VST even when it is related to the use of an openGL libarary. Why is the Transfuser-2 fully drawn by Cubase when it is closed and then opened again? I can not explain this.

With kind regards,

Very likely because of an outdated OpenGL rendering strategy and because once again the proper handling of HiDPI requires interfaces only available in VST3 that developers have to maintain. This is valid for every DAW. Again as you could see it seems that Fabfilter is not HiDPI aware on Ableton Live. It is not because a window is properly rendered in another DAW that this window is properly declared as HiDPI. In our benchmarking Cubase is really not the worst player when it comes to trying to deal with VST 2 plugins on a hybrid HiDPI environment. And there is definitely no flawless player, it’s impossible as long as the manufacturers wouldn’t have moved to VST3.

OK, I have to wait for AIR Music response on this matter. Close the subject on Transfuser-2

So what about the redrawing of open VST’s in Cubase? This has nothing to do with VST2, VST3’s and occurst occasionaly with every o[pen VST window while working in Cubase.

And is there some setting that always keeps the VST’s open wherever you may click on a screen (wether it is inside or outside cubase).

With kind regards,

Check the preference for VST Plug-in Editors “Always on Top”:

Hi Arne,
"Always on top"works only when you click inside Cubase. When you click somewhere outside the program ALL open VST windows just disappear. I even have the same result when clicking inside a VST window that open a the Windows File Explorer. If the Windows File Explorer open all open VST window just disappear. How can you then easily drop and drag to an open VST window.

So how can I make this normal Windows behaviour, just always let the open VST windows open even when you click OUTSIDE the CUBASE program.

On Mac at least, when you drag a file from Finder to Cubase the vst window appears again after a second or so and you can drop on it.
Maybe it is the same with Windows. Did you try waiting a bit after you drag?

Hello. Fabfilter works great in Ableton in HDPI mode! I got both. Cubase and Ableton. And I need to say, that Ableton works amazing on Windows in HDPI. You can scale it as you want and all looks smoothly and clear. Regarding Cubase honestly it’s so buggy! :frowning: And it’s not regarding the third party plugins. I am talking now about stock Cubase graphic issues! Stock! And it makes me sadly. Come one, Steinberg! The end of 2021 is here! I was added another graphic issues on my topic here:

Hi @Alexander_D

So far all our tests show that the plugins are not HiDPI aware on Ableton. The app itself is also not HiDPI aware. They are rescaling everything internally and not using the API offered by Windows. The 3rt part plugins seem to all be rendered LoDPI. We’re happy to be proven wrong but here’s a the screenshot, left is Ableton, right is Cubase:


Ok, it’s regarding 3rd plugins. But are you agree that the main Cubase GUI is not perfect in HDPi in Windows? And is it will be fixed? Or I need to buy new not 4k display ? :frowning:

I agree that Cubase isn’t flawless in this regard. We are aware of it, it takes more time and focus to revamp the entire GUI than we initially planned. Always keep in mind that we don’t have unlimited resources and that any time spent on HiDPI means less time for other long-awaited features. I cannot promise anything but an iterative process here, from one version to the other.


Cubase performs all in all comparatively fine next to other competitors when it comes to handling HiDPI. We are regularly testing most of competitors and they all come with pros and cons. So far we are not aware of any competitor that is truly HiDPI-Aware and has solved every internal and external issues. I wouldn’t mind admitting that there is one, but we are not aware of it so far. Cubase offers a balanced compromise between two worlds here and shouldn’t be branded as the bad pupil of the class every week.

To future posters: I would really like to stop being confronted every week with claims of this sort. A closer look at every corner of every app will show you that competitors aren’t flawless as it is often claimed here. We welcome any bug report, we do, but as long as it is specific and that the discussion doesn’t fall into rhetorical scapegoating.

Thank you for your reports in advance! :slight_smile:


I don’t say, that you are don’t working. Don’t be wrong… Regarding the concurrents. Well, Ableton is fully work great in HDPI ( I am talking now about stock GUI). And you can scale it as you want. All looks clean and bright. I understand you that probably you are boring regarding the posts like this. Soory, but please understand me too. I was pay for the product and I can’t submit the ticket from Russia! Is it ok??? Or where I need to post about the bugs? It’s the strange… Is it ok that I purchased the product and can’t get the support??? NO tickets, also on this forum - don’t post about problems with HDPi. I like Cubase a lot and want work without these issues… As you can see, I am not only the one who told and post about problems with HDPI. It’s realky hard to work with blurr fx. Seems that it’s not the main problem for Steinberg. All is clean.
Sorry once again…

I understand that this is unsatisfactory status quo for you.
We are welcoming to answer and address any issue related to HiDPI specific to Cubase as long as there is readiness to accept when we come to the conclusion that some of those issues are not due to Cubase but to the VST manufacturers, and that competitors are very likely not dealing with it in any way better than Cubase.

Is there not a way for cubase to have some kind of plugin hidpi rendering internally, like reaper 6 does ?

Thanks for your answer. Ok, please check my post here. Just adeed another two issues. And it’s only Cubase GUI.


A post was split to a new topic: VST Windows disappearing when attempting to drag&drop files from the Windows Explorer

I am constantly having the same issues and most of my plugins are cut and I just cannot use them with scaling set +125% in Windows and -25 in Cubase. All of the plugins are cut. But VST2 works just fine. But here is another thing. You cannot sidechain VST2 plugins at all. There is no way to do this, it was just removed. So now, I cannot use Soothe2 and I just have to get a 1080 monitor for my laptop, which is kind of ridiculous.

Are there any news for this, is it going to be fixed? No other DAW does this (Reaper, Ableton, Bitwig, Pro Tools)

I honestly don’t care that much about the blurriness, the only thing I care about is screen’s real estate. Is there any way to force VST3 to run in 100% HIDPI scaling (which means no scaling) regardless of Cubase? The solution would be something like in VST Plugin Manager → Plugin → Disable UI scaling/ HIDPI for the selected plugin.

Thank you


I assume you are using the “Allows Windows to rescale” option for the VST2 right? Could you identify which manufacturers/plugins here?
