--- Comment #6 from Duncan <1i5t5.dun...@cox.net> --- Created attachment 133731 --> https://bugs.kde.org/attachment.cgi?id=133731&action=edit kwin_x11 --replace output, switching windeco oxygen > plastik > oxygen (In reply to Vlad Zahorodnii from comment #5) > Can you apply the attached patch and check if there is any > "Aaaaaaargggggghhh! OpenGL context is not valid" No such message (and I double-checked my build log to be sure the patch had applied). There's some nasty-looking output logged but not that. But in case it's useful... Here's the log from a kwin_x11 --replace >kwin.debug 2>&1 , while already having the windeco kcm open so I can immediately test switching to an aurorae-based one. I did the replace with the windeco set to oxygen, switched it to plastik, applied, switched it back to oxygen, applied, and did another replace to stop logging. The first set of OpenGL/Mesa/etc info is from the initial replace. The second is triggered by the apply after switching to plastik. You can see the nasty-looking output after it from trying to load plastik (my previously preferred aurorae-based blacksquare has similar output, but plastik is the kde-shipped aurorae-based windeco so I did the log with it). The third is from the apply after switching back to oxygen -- no nasty output. (The final three lines of XCB BadWindow errors are unrelated; I was launching recursive pdmenus in konsole to run the final replace from there.) (I'm pretty much switched to wayland now, having hack-patched a local workaround to the last real irritating bug #429177 on that today. So I quit plasma/wayland to CLI (no *DM installed here) and start plasma/X to test X-side-only bugs like this, now. I had my brain full of wayland bugs, workarounds and hack-patches with the switch so it took me a few days to apply this patch and get a log.) -- You are receiving this mail because: You are watching all bug changes.
