--- Comment #4 from Zamundaaa <[email protected]> --- There dummy shader can't help. If it doesn't work on the hardware, it simply has to fail and fall back to software rendering. For the moment, you *could* attempt to patch KWin to reduce the amount of instructions in the colormanagement.glsl file (maybe delete the tonemapping code), but it's not a long term solution. Software rendering should absolutely not be that slow though, the buffer pinning is probably the bigger problem. Unfortunately at this point, it seems rather unlikely for the radeon driver to see fixes for it, but you can try creating a report for it at https://gitlab.freedesktop.org/drm/amd/-/issues -- You are receiving this mail because: You are watching all bug changes.
