Bug ID: 57975
           Summary: screen shaders don't work in BigPEmu.exe
           Product: Wine
           Version: 10.0
          Hardware: x86-64
                OS: MacOS
            Status: UNCONFIRMED
          Severity: minor
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]

BigPEmu is an Atari Jaguar emulator, it runs Atari Jaguar games fine under Wine
Stable 10.0 on macOS 11. The problem is there is a "screen effects" feature
(which are like screen shaders in RetroArch, used to emulate old CRTs, etc)
which doesn't work. By default, BigPEmu uses OpenGL (BigPEmu main menu > Video
> Video Plugin > BigPEmu_Video_OpenGL) but can also be changed to use D3D12

which will cause it crash at startup on macOS 11.

Steps to reproduce:
1. launch BigPEmu 1.18 with the following options (also opens a console):
wine ~/BigPEmu_v118/BigPEmu.exe * -conout

2. use backspace/enter to navigate backward/forward in BigPEmu, go back to the
main menu, then Video > Screen Effect > choose any screen effect

3. an error message pops up: "Failed to set the selected screen effect. It may
be incompatible with your hardware or video plugin. You can enable logging and
check the log for more details."

4. check the console which shows this error: "[1;31mError: Graphics hardware
isn't equipped to run screen effects. If this error occurs with
SM5.0-compatible hardware, try updating your graphics drivers."

tested with BigPEmu 1.18 for Windows x64
