I am having significant issues with plugins and Cubase freezing for a range of plugins when used on a multi-screen configuration. Cubase Pro 10.0.20 on Windows 10 Pro x64 (1903) with nVidia GTX 1650 graphics connected to Dell P2314T MultiTouch 1080p (DisplayPort) monitor set as primary and Dell U3417W UltraWide 3440x1440 (DisplayPort) set as secondary monitor. With 100% scaling on the 1080p and either 100% or 125% scaling on the UltraWide secondary monitor, I face the following problem with Arturia V Collection 7 (and previous ones, since their scalable UI was introduced) as well as the MasteringTheMix plugins LEVELS and REFERENCE:
-
Add/open VST on primary monitor - all ok
-
Move to secondary monitor - all still ok
-
Move back to primary monitor - all still ok
-
Close on primary monitor - all ok
-
Reopen and retest - all ok.
-
Add/open on primary monitor - ok
-
Move to secondary monitor - ok
-
CLOSE on secondary monitor - appears to be ok
-
Open again, opens with blank edit area - moving to primary monitor does not help
-
Try to close, it freezes Cubase completely, needing the process to be killed! Because it is killed, no crash dump log available.
-
After restarting Cubase, try to add/open again, and now it tries to open on second monitor with problems as per step 9.
-
Only way then is to kill Cubase, disable extended screen mode, launch to get it back on primary screen, and then close it in that mode.
Have been working with both Arturia and MasteringTheMix but have not been able to get it resolved with them. The issue does not occur on REAPER, but does (but without the issue of having to kill the process) in Cakewalk/SONAR Platinum. Not tested in others, but seems to be something to do with the initial drawing process when on the secondary screen. As its more than just one plugin manufacturer, is this something Steinberg can/should be looking at?
Interestingly, MasteringTheMix use OpenGL in their plugins - not sure about Arturia, but I suspect they might also be doing the same. Have also had issues with Cherry Audio’s Voltage Modular when it is configured to use OpenGL - so there appears to be a conflict going on between OpenGL in Cubase and the plugins.
