I've been having major graphics issues lately, especially when I turn on VBoxSVGA, which I use with 2D and 3D acceleration enabled. Just now after experiencing some weird issue's I'll go into in a bit and trying to reboot my machine, I got a message box telling me VirtualBox had to abort and to submit a ticket. I'm attaching a log file for the ticket, as well as the VM Guest configuration file. As far as I know, everything is up to date and configured correctly. I'm also attaching the output of lspci (for my host's graphics card) and a partial dump of dmesg as there are some warnings from VB kernel modules. Some background: Basically, everything seems to be working intermittently graphics-wise. All the issues seem to be occurring due to crashes inside C:\WINDOWS\system32\VBoxSVGA.dll, including frequent windows in Desktop Window Manager (dwm.exe). Additionally, sometimes I am getting the error ""Display driver failed to start; using Microsoft Basic Display Driver instead. Check Windows Update for a newer display driver."". When this happens I have no choice but to restart because the guest's screen becomes totally black with a working cursor and a blurred version of the VB bios screen overlayed in white. There is no way to resolve this without a reboot. When things get really bad, pretty much all apps refuse to launch (though the ones already launch still work) and they fail silently (this is really ironic and frustrating as this includes debugging apps), though for each attempt I see an error relating to VBoxSVGA.dll in the Windows Error Log. I am attaching several days worth of Windows Error Logs (Application Logs) in XML format in the hopes they contain some information. I'm also attaching an HTML export of the Windows Error Reports that were generated. (Unfortunately I didn't have saving minidumps enabled at the time.) When this whole ""nothing will start"" phenomenon occurs a program that I'm frequently trying to use -- a 3D modeling program called Autodesk Fusion 360 -- actually freaks out because it will keep trying to restart a Chrome WebView process ad infinitum (obviously the ad infinitum bit isn't on VirtualBox). I've included a stack trace from a minidump of one of these crashes as it's one of the few minidumps I have. (I can't attach the minidump itself as the memory contains proprietary content.) If anyone could offer any help, it would be greatly appreciated. I'm happy to assist with debugging this in any way I can. ",defect,new,3D support,VirtualBox 6.0.6,,,,Windows,Linux
