Bug ID: 51769
           Summary: ClientSideGraphics=N with 30-bit color depth makes all
                    graphical applications crash
           Product: Wine
           Version: 6.17
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: critical
          Priority: P2
         Component: winex11.drv
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

If ClientSideGraphics=N and Xorg->DefaultDepth=30 all graphical Windows
applications crash on startup.

BTW I enabled this option a long time ago and I've no idea why. Does anyone
know if this option is still beneficial for anything in 2021? Or it's been
deprecated a long time ago?
