The patch disabled the use of the GPU by the library (it sets an internal disableGpu variable to true). There's another internal flag called EnableThreadedCompositing, but it seems only disabling threaded compositing isn't enough to fix the crashes. So the way I see it, we have two options: 1) Patch kwin so that it defaults to XRender and patch Qt webengine so it disables the use of the GPU (both only with nouveau, of course). That would fix kwin and all kde applications using the library while other applications would be able to use it. I understand that breaks the experience for people that have a graphics card that works fine with nouveau, but option 2 breaks it equally and this feels to me less intrusive. Option 1.5 would be to allow setting an USE_NOUVEAU_GPU_I_KNOW_WHAT_I_AM_DOING environment variable to "disable" the patches and allow people to test their hardware and report working cards to us so we can create a cards whitelist that is read by kwin and qtwebengine, and that we can update via a (new) "nouveau-whitelist" package updated regularly. So at some point in the future, people with working cards will just feel their desktop is faster after they update their systems. 2) Disable the Nouveau 3D/DRI driver in Leap as it's currently done and try to get upstream to fix it. This, indeed it's much easier for us, as people will just see bad performance and switch to the propietary nvidia drivers. I'm not sure which option I prefer. I think I like option 1 (or 1.5) more, but option 2 doesn't look bad either (and is, in fact, much easier for us). Opinions? -- You are receiving this mail because: You are on the CC list for the bug.
