[email protected] changed: What |Removed |Added ---------------------------------------------------------------------------- Resolution|DOWNSTREAM |--- Status|RESOLVED |REOPENED Ever confirmed|0 |1 --- Comment #8 from [email protected] --- Some more updates: I think this might not be a downstream problem. I did more tests. Using Fedora 40 KDE Live image under guest vm with no 3d acceleration , and the problem doesn't exist. So i dig deeper (recompile kpipewire and add some logging) and found that 1) memfd is used when no 3d-acceleration 2) dmabuf is used when 3d-acceleration with Fedora 40 KDE live image in Guest env. and KDE is 6.0.3. So there must be something wrong (kwin? kpipewire ? or mesa?) on determine which (memfd/dmabuf) to use when there's no 3d-acceleration or have 3d-acceraltion At least on KDE side, we should do the right determination to use memfd when no 3d-accerlation (because dmabuf is buggy under this circumstance) since it has been done correctly before. -------------------- I also created an issue on mesa side (before my Fedora 40 tests) : https://gitlab.freedesktop.org/mesa/mesa/-/issues/13825 and also found some bugs might relevant: https://gitlab.freedesktop.org/mesa/mesa/-/issues/9375 https://gitlab.freedesktop.org/mesa/mesa/-/issues/12341 -- You are receiving this mail because: You are watching all bug changes.
