           Summary: S.T.A.L.K.E.R. Anomaly : lighting problem with
                    flashlight?
           Product: Wine-staging
           Version: 5.3
          Hardware: x86-64

Hello,

I remember playing other STALKER mods 1 ou 2 years ago without problem (on
wine-staging 3.21 IIRC) . But here, with wine-staging 5.3, on Fedora 31, with
NVIDIA drivers 440.64 on a RTX2060, with DXVK 1.5 , I can't get the flashlight
to work: I press the key for the flashlight, I hear its sound, I see a brief
flash but it doesn't light anything after that.

I have tried the rendering modes available to the games: DX8, DX9 , DX10 and
DX11 (); DX10 and DX11 crash with an error in D3DX11GetImageInfoFromMemory /
function CRendeer::texture_load / file ..\xRenderDX10\dx10Texture.cpp for the
ui_font_hud_01.dds file.

DX8 and the various DX9 modes make the game work flawlessly, but I don't have
the flashlight...

I'm no expert at all, but it seems that there was a rendering issue introduced
between the last version of wine 3 and the first version of wine 4, because as
far as I remember it happened at this time. And I had to reinstall wine-staging
3.21 to be able to continue playing because wine-staging 4.0 had this lighting
problem already.

I can attach log files or debug traces if needs be.

Thanks.
