corrupted screen

F.E.A.R. 2: Project Origin, a 32-bit Direct3D 9 game, has severe rendering
corruption when using WineD3D's OpenGL renderer in the new WoW64 mode with the
proprietary NVIDIA driver.

The image has heavily distorted, bright colors. After switching away from the
game with Alt-Tab and returning to it, the bright color distortion disappears,
but the image remains much too dark. Loading another level brings the color
distortion back.The graphical corruption in the game may change between runs
rather than remaining constant: orange hues dominate in some instances, and
blue in others.
Changing graphical settings between low and maximum has no effect on the
graphical corruption.

The problem is reproducible with the new WOW64 mode with multiple proprietary
NVIDIA driver versions, including 595.x and 615.71.09. It does not occur with
Nouveau/Mesa 26.2.3. in WOW64 mode.

The problem is independent of the window-system and OpenGL platform paths I
tested:
X11 /XWayland / native Wayland
EGL and legacy GLX

The results of the tests:
Wine 10.17, new WoW64: correct rendering but slow performance
Wine 10.18, new WoW64: corrupted rendering, performance is good
Old shared-WOW Wine-11.18 build: correct rendering
New WoW64 with Nouveau/Mesa: correct rendering
New WoW64 with proprietary NVIDIA and DXVK's d3d9.dll: correct rendering
New WoW64 with proprietary NVIDIA and WineD3D/OpenGL: corrupted rendering

Setting strict_shader_math=0x1 does not change the problem.

I bisected the regression. The first bad commit is:
a2906847c0c94c119b74c94f0fc606ca9e9f140d
opengl32: Support wow64 buffer storage and persistent memory mapping using
Vulkan.

With the parent commit, the game is very slow, but the image is rendered
correctly. With a2906847c0c94c119b74c94f0fc606ca9e9f140d, the performance is
good and the rendering corruption appears.

The regression commit is also the commit that was intended to address the
general new-WoW64 OpenGL performance problem from bug #55981. I also reported a
separate proprietary-NVIDIA/new-WoW64 performance problem as bug #60354.
However, this report concerns a reproducible rendering-correctness regression
rather than reduced performance.

I also tested the following later commit:
b22af9f012e973c34aed781bdcf81d03d408de03
opengl32: Use Vulkan-backed buffer storage only when GL_MAP_PERSISTENT_BIT is
specified.

The rendering corruption is still present with that commit. This suggests that
the affected path uses persistent mapped buffers and that limiting the
Vulkan-backed implementation to GL_MAP_PERSISTENT_BIT does not resolve the
problem.
