Can you be more specific about what stopped working means? Did the game have corruptions? Was is crashing on start-up?

And just to be clear you deleted ~/.cache/mesa_shader_cache/ ?

I'm sorry but I can't be more specific than that the game "World of tanks" that i've been playing didn't start after driver update, no window. Nothing.
When It didn't start I tried to run 64 bit cube.exe from LunarG Vulkan SDK, and it did run.
Then I tried the 32 bit cube.exe from the LunarG SDK, it crashed. Weird becouse it run before driver update, and 64 bit cube.exe still worked.
I didn't know what to do, (i'm no genious), so I deleted ~/.cache/mesa/ and ~/.cache/radv_builtin_shaders, and voila, 32 bit vulkan apps in wine starts working (32 bit cube.exe and dxvk)

Do you recall what version you updated from?

No, but probably from previous oibaf.
I don't know how oibafs 32 bit vs 64 bit package dependencies are set up, if there are any, but could it be that i had a temporal version mismatch between 32 and 64 bit version that trigered the bug? I don't know.
I've tried to reproduce it but failed :-(

My computer reproduced bug!! 

64 bit cube.exe working and 32 bit cube.exe and 32 bit dxvk not working before deleting ~./cache/radv_builtin_shaders

I don't know why or how but i grabbed some output so you can try figure it out :-)


Driver versions = 18.1~git1804190730.0e1079~oibaf~b

radv: place pointer length into cache uuid

Thanks to reproducible builds, binary file timestamps may be identical
for both 32bit and 64bit packages when built from the same source.
This means radv will use the same cache for both 32 and 64 bit
processes, which leads to crashes.

Conveniently there is a spare byte in cache_uuid, let's place the
pointer size there.
