Workstation 16 Pro: BSOD while searching text by UltraEdit in guest os Windows 10 LTSC 2019 and 20H2

Generally UltraEdit will show "End of file, searching from top" when it reach end of file while searching text by F3 key.

But in guest os(Windows 10 LTSC 2019 and Windows 10 20H2) it cause BSOD.

I have tried on my desktop and laptop. Both of them have the same problem.

UltraEdit version I tested: 25.10.0.62 /  27.10.0.108

Normal:

thanks for reporting scott0122. We managed to reproduce this in-house with UtralEdit.  There is a workaround if you're willing to try.

The workaround is:

Power off the VM and add

to your .vmx file, then power it back on.

This will disable GDI HW acceleration only and have no larger effect.

Update:

Guest hardware compatibility: W16.x/ESXI7 + Accelerate 3D graphics: on -> BSOD

Guest hardware compatibility: W16.x/ESXI7 + Accelerate 3D graphics: off -> fine

Guest hardware compatibility: W15.x/ESXI 6.7 + Accelerate 3D graphics: on -> fine

Guest hardware compatibility: W15.x/ESXI 6.7 + Accelerate 3D graphics: off -> fine

Guest hardware compatibility: W16.x/ESXI7 + Accelerate 3D graphics: on + guestInfo.svga.wddm.enableGDIHW=FALSE

There is another issue.

Left application is PrusaSlicer  2.3.0 alpha2(OpenGL app). You can download here: Releases · prusa3d/PrusaSlicer · GitHub

Right application is Chrome.

Their correct behavior should look like the picture.

Hi,

Can you try setting an environment variable SVGA_MSAA=0 before invoking PrusaSlicer?

Do you still see blank screen in the PrusaSlicer window?
