Created attachment 147906 [details] Showing Konsole, which is totally opaque, though set to be partially translucent, with a blur behind it. SUMMARY *** After update to most recent version of kwin, a litany of bugs are present. One among many is that *all* desktop effects, save screen-edge highlighting, are non-functional; enabling, disabling, reinstalling, etc. has no effect. Screen edge highlighting is now present even though I have it set to disabled. *** STEPS TO REPRODUCE 1. Enable your favorite effect 2. Observe its total absence 3. Disable screen edge highlighting 4. Observe its presence SOFTWARE/OS VERSIONS Linux: Arch 250-4-2, on Zen kernel 5.17.1 KDE Plasma Version: 5.24.4 KDE Frameworks Version: 5.92.0 Qt Version: 5.15.3 ADDITIONAL INFORMATION This update has several breaking points. Scrolling in any window now causes screen tearing. Latte-dock's effects are also disabled, and latte is not respecting settings of opacity, shadowing, and so on. Window aurorae are partially missing. Minimizing and tiling are also now visually glitchy, and the visual glitches of Discover, long known, are increased in severity. Screen-tearing at the edge of moving windows is also present.
Are you on X11 and compositing got turned off? Can you attach your ~/.config/kwinrc file?
Wow(In reply to Nate Graham from comment #1) > Are you on X11 and compositing got turned off? Can you attach your > ~/.config/kwinrc file? Well, this looks like it was it, actually. that indeed had somehow been set to false as a result of the update.
Yeah, this means KWin thinks your openGL capabilities are too unstable to do compositing. See Bug 452344. *** This bug has been marked as a duplicate of bug 452344 ***
