--- Comment #1 from Nikolay Sivov bunglehead@gmail.com --- Is this fixable with native d3dcompiler, when used with the same build? I don't know if they cache compiled shaders, so it might necessitate testing in a new prefix.

--- Comment #2 from Nikolay Sivov bunglehead@gmail.com --- I can answer that myself now, it is in fact fixable with a native compiler for both Legend of Grimrock and Legenf of Grimrock II. Corruption on starting screen I see is different though, it looks like constant pink noise covering the whole screen. Strangely that applies only to the start screen, not to the quit menu for example.

--- Comment #3 from Gijs Vermeulen gijsvrm@gmail.com --- Is this still present with wine-git & vkd3d-git? I don't see this with Legend of Grimrock II. I am running a GTX 1080 with blob driver 535.113.01.

--- Comment #6 from Nikolay Sivov bunglehead@gmail.com --- Created attachment 76134 --> https://bugs.winehq.org/attachment.cgi?id=76134 shader
I found a shader responsible for this pixel noise. This appears to be a miscompilation wrt semantic handling. With current vkd3d I get this:
ps_3_0 dcl_color v0 dcl_texcoord0 v0 mov r0.xyzw, v0.xyzw mov oC0.xyzw, r0.xyzw
while correct output is
ps_3_0 dcl_color v0 mov oC0, v0

--- Comment #7 from Nikolay Sivov bunglehead@gmail.com --- Originally reported red segment seems to be about matrix majority handling - game is passing D3DCOMPILE_PACK_MATRIX_ROW_MAJOR flag, that was ignored in vkd3d until recently.
