It indeed compiled much faster than I expected. I was able to test the crash again, but got different results. I have been unable to catch plasmashell getting SIGSEGV. It is just Xwayland who gets SIGABRT twice and then exits. I have already seen this before (not back when I opened this report) but plasmashell would at times still get SIGSEGV. This doesn't seem to be the case anymore. Some time ago I found the crash this report is about can be worked around with 'QT_QPA_PLATFORM=wayland-egl', which will force all Qt applications into native Wayland rendering (and I guess plasmashell is one of them). So Xwayland can be considered suspect of this issue. If there is a bug in Qt, Xwayland or another library, then I imagine the SIGSEGV was caused by either of these messing up before mesa finished rendering their items (and thus causing the miptree not to be created properly). I guess your patches just make mesa less vulnerable against this. I'm enclosing the log for one of the crashes, with INTEL_DEBUG=fbo,mip. I have no actual knowledge about rendering, so maybe you find more meaning in it. Thank you very much.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
