Bug ID: 49700
           Summary: Apps crash on discrete NVIDIA card with X error
                    BadMatch: NV-GLX when emulated virtual desktop is
                    enabled
           Product: Wine
           Version: 5.14
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: wine-bugs@winehq.org
          Reporter: rockorequin@hotmail.com
      Distribution: ---
I'm running Ubuntu 20.04, wine-devel 5.14, nvidia 450.57-0ubuntu0~0.20.04.2 on
an Optimus system with prime-select set to on-demand. I'm also running
dxvk-1.7.1 because the games I've tried crash without it.
With a clean wine prefix except for the graphics set to emulate a virtual
desktop of 1920x1080, running a game with the command
"__NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia wine <exe file">
fails with an error like this:
Error of failed request:  BadMatch (invalid parameter attributes)
  Major opcode of failed request:  156 (NV-GLX)
  Minor opcode of failed request:  43 ()
  Serial number of failed request:  334
  Current serial number in output stream:  335
With a clean wine prefix (ie no virtual emulated desktop), the games run
without issue, and in wine 5.0.1 they run with and without an emulated desktop.
Both dx9 and dx11 games crash - I don't think DirectX is relevant here because
the crash is when the game first tries to create a 3d window.
