I get BSODs in a Win 10 guest running on a Pop OS 20.04 host. The BSOD is in vm3dmp.sys, with the error PFN SHARE COUNT.
Using dedicated 3d graphics acceleration on a ThinkPad T560 (Nvidia), VmWare being the only application to use the dedicated graphics card, the host is using integrated Intel graphics for everything else.
This is reliably reproducible by running Cubase 10.5 Elements, and trying to add an audio track, causing an instant BDOD. I have no other display adapters installed (I did have Citrix Workspace, but I uninstalled that and this didn't change anything). I found a couple of other posts saying that adding:
guestInfo.svga.wddm.enableGDIHW="FALSE"
in the .vmx file would solve the problem, and indeed, this has so far prevented further BSODs. This apparently prevents VMWare using 3d acceleration for the Windows GDI API, but continues to allow other 3d acceleration (although I haven't tested whether it is still accelerated for other applications). So it appears to be a bug in the VMWare display driver.
Posting this in case it helps others, and to increase awareness of this bug to VMWare. Would also be interested if there are any other solutions to this issue.
