Backbone Crashing Cubase 11 because of High DPI Mode

Hello,

i work on cubase all day of the week :wink:

Cubase started crashing randomly only if i’m working with a backbone instance.
( it generated crashdumps everytime )

only thing i have changed is turning “allow high dpi” to OFF in backbone this morning because i was resizing them everytime i had to edit them ( showing really too big ), and it was annoying.
My C11 has high dpi option ON.

it seems turning high DPI mode ON again solved it.

BUT backbone doesn’t remember the resizing i’ve done last time i opened it
( i’ve opened all instances and resized them ) and sometimes randomly open in such BIG size, it is impossible to resize…

Tech : New computer ( 2 months ) Win 10 fresh install, C11, only audio software.
Asus X299 MB, I9 10980X, AMD R7 250 gfx card
Monitors :
Main 43" / scaled 150% ( 4K screen )
Secondary 27 " / scaled 100% ( 1080 screen )

Any tips / infos welcome :wink:

Win 10, Monitors :
Main 43" / scaled 150% ( 4K screen )
Secondary 27 " / scaled 100% ( 1080 screen )

i have a lot of third party plugins ( even bridged old 32 bits )
Backbone is the only one crashing cubase.

it is a relatively “clean” crash as it generates Dumps.

i tried all possibilities :
C11 HDPI ON - BB HIDPI ON > crash
C11 HDPI ON - BB HIDPI OFF > crash
C11 HDPI OFF - BB HIDPI OFF > crash

it happens when moving windows, or when the plugin open on my non-hdpi monitor ( ie 1080 monitor )

is there anything i can do to solve this ?

right now i a finishing a project for a commercial with 20 backbone instances and tight deadlines, and i have to wait 20min for my huge session to reload after every crash…
i’m pretty upset :confused:

Is there any reason you did not upload some?

Thansk
@steve : yes, knowledge & time, i’ll do this next crash :wink:
i just copy-paste what is inside the file ?

right now with HDPI disabled in C11 that works BUT a lot of plugins are not usable ( window badly resized, parts of the UI not visible )

i already applid this fix also : https://forums.steinberg.net/t/cubase-10-5-hidpi-on-windows-10/149114/18

Please, no. See Forum Guide (New here? Read this.)

thanks Steve !

to sum up :
Win 10, Monitors :
Main 43" / scaled 150% ( 4K screen - HDMI )
Secondary 27 " / scaled 100% ( 1080 screen - VGA )

i have a lot of third party plugins ( even bridged old 32 bits )
Backbone is the only one crashing cubase.

i got a stable state with :

Cubase HDPI = OFF
Backbone HDPI = OFF

disableing this fix

( = going back to normal : uncheck "use this setting to fix scaling problems… " + uncheck "override high DPI scaling… " )

And turning this OFF >>
NB : that was NOT turned off when the crash happened ( for crash dump analysis ).
in windows settings :
settings > display > advanced scaling settings > “fix scaling for app” = OFF
( this was also the culprit of cropped plugin windows in my secondary display )

In this state i still have the cubase menu ( from the top menu bar : file / edit / projects … )
not showing at the right place & font size … but it’s manageable
And i don’t have plugins opening with crazy size.

So all HDPI off is the way to go it seems

NB : this is a brand new PC ( from 3XS - optimised audio workstation ) , fresh win 10 install,
dedicated to only DAW work

I cannot upload any crash dumps as the maximum size seems to be 4Mb and my crashdumps weights 11.1 Mb,

hahaha… :clap: :clap: :clap:
