rainbow-colored speckles on wayland #52

Closed greyltc closed 5 years ago

greyltc commented 5 years ago

I've got this working fine (besides some screen tearing/vsync issues) on my Arch laptop with an Intel GPU and a GeForce GTX 960M. I ended up having to launch like this to get it to work properly though:

ENABLE_PRIMUS_LAYER=1 VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/nv_vulkan_wrapper.json:/usr/share/vulkan/icd.d/intel_icd.x86_64.json optirun ${THING_TO_RUN}

When I use it under gnome-shell on wayland the DX11 & proton-4.11.3-based thing I'm launching ends up having rainbow-colored speckles all over it (though the performance seems fine). When I switch gnome to run on X and repeat the same thing, the speckles are gone and everything seems to work fine.

Any idea how to fix that?

No, I didn't find time to test and debug this myself. I assume, it's the same problem as #32. So far we've established that the artifacts appear to be created after the image is copied by primus_vk (and before it's rendered on the the screen). However I don't know yet what component is misbehaving.

Yes. Same issue, sorry for the dupe!

felixdoerre commented 5 years ago

No problem. The title of that other issue is not really descriptive :).

I've improved the title of the other issue and close this one as duplicate.
