[Bug 57975] BigPEmu 1.18: screen effects (shaders) don't work

[WineHQ Bugzilla]

--- Comment #3 from ToastyBug  ---
Since Wine Devel 10.3, the D3D12 plugin for BigPEmu no longer causes the app to
crash at startup, and it is somewhat usable (games work, but there are other
rendering errors in the app)

This original issue still occurs when the renderer is set to D3D12
(BigPEmu main menu > Video > Video Plugin > BigPEmu_Video_D3D12)

With D3D12 rendering, some of the screen effects can be loaded, but they
display either a blue or white screen, or some other undesired effect, and in
all cases don't work when playing a game
