Bug ID: 50317
           Summary: Unusable performance/system locks up in 3D
                    applications since 5.14
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: P2
         Component: winex11.drv
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

Upon launching seemingly any intensive 3D application via wine the system
becomes unresponsive and Xorg has 100% CPU usage.

Arch Linux OS, Linux kernel 5.9, Nvidia GTX 970 proprietary drivers 455.45.01
Issue happens on any wine release since 5.14.
Issue goes away if I use the 'virtual desktop' mode. Possibly related, I use
two monitors.

Bisecting it leads to commit 5491e939bc22f0ab479aec6b8a525be9c5ff5e35

Hello,

Not all applications uses the same 3D api.

Please, cite the applications that you know are affected by the issue and, if
there is a freely and legally download available for one of them, add the link
to the vendor website and 'download' keyword to the proper fields.

Regards.
