OpenGL/Vulkan Battlefield Bad Company Shader Issues

[stride21]

The crash happens when you look in a certain direction while riding in the truck after the opening cutscene, if you look elsewhere you can avoid this crash.

Here are some of the errors around when it happens:

E {rsx::thread} RSX: Src type 3 used, opcode=0x1, dst=0x1BA01BB s0=0x1BC01BB s1=0x1BB01BC s2=0x1BD0119
E {rsx::thread} RSX: BRK opcode found outside of a loop
E{rsx::thread} RSX: Unknown/illegal instruction: 0x3f (forced unit 1)
E {rsx::thread} RSX: Src type 3 used, opcode=0x1, dst=0x1340137 s0=0x1370133 s1=0x13C013B s2=0x13C0137

Classic heap corruption, rpcs3 ends up compiling trash and dies.

I also found another place where it crashes and seems to be the same issue. Also, found a E {rsx::thread} RSX: Depth texture bound to pipeline with unexpected format 0x9B error so I think I'll open an issue on that soon.

Those errors are not fatal. They cannot crash the emulator.

This issue is now fixed with #5076

[stride21]

Reopening the issue because it still seems to have shader issues but it just no longer crashes because of them.

Is it still an issue?

[stride21]

It still happens in the beginning of chapter 1 and the middle of chapter 2 when artillery is being used. It doesn't cause an instant crash but it can eventually cause a crash unless you clear the shader cache.

Any update? Looks like a duplicate of the RSX desync metabug.

[stride21]

@kd-11 Its still an issue. I can post else where and close this issue if you want.

I have this issue too on Gran Turismo 5 RSX: BRK opcode found outside of a loop And when it happens the whole emulator Frezzes and stops.

[kd-11]

That is an obvious sign of emulator desynchronizing and RSX trying to process garbage.

This issue is fixed on master for both OpenGL and Vulkan.
