0%
Description
Game Name?
Resident evil 4 (RE4)
Game ID?
G4BP08
What's the problem? Describe what went wrong.
White textures and shadows ingame
What steps will reproduce the problem?
Start new game, watch FMV, when 3D graphics start, you'll see the problem.
Which versions of Dolphin did you test on? Does using an older version of Dolphin solve your issue? If yes, which versions of Dolphin used to work?
Latest working is 5.0-1650.
After OGL/Vulkan: Drop destination alpha pass 5.0-1653 in all versions I see this problem. Gameplay is impossible.
What are your PC specifications?
Xiaomi Mi4c, Adreno 418, Android 7.1.1, OGL ES 3.2.
Is there any other relevant information? (e.g. logs, screenshots,
configuration files)
This problem is also on Adreno 530 devices and Mali.

May you try if this bug also happens with the cached interpreter or the software video backend?
But it is likely because of the removed destination alpha fallback. It might be that we'll require dual source blending for this game: https://www.khronos.org/registry/OpenGL/extensions/EXT/EXT_blend_func_extended.txt -- But as far as I know neither Adreno nor Mali ship this extension.

- Subject changed from Problems with shadows on android in RE4 [Short description of your bug here (~10 words)] to Problems with shadows on android in RE4
- Status changed from New to Won't fix
- Regression changed from No to Yes
- Regression start set to 5.0-1653
The destination alpha fallback was dropped intentionally, so I don't think it will be coming back. (If any dev disagrees and wants to re-add it, feel free to reopen this issue.)

But how it work on Vulkan? This extention only for OGL or not?
Because on Vulkan on my device it also has the same problem.

Sorry, look at AIDA64, as I understand it is Dual Source Blend Operations. It's unsupported at this time in drivers.
