Created attachment 156442 [details] As you can see, only a part of the app's window is blurred SUMMARY *** I have a semi-transparent theme in the Konsole app and the compositor takes care of the blur effect. However, when I put the app to windowed mode from maximized mode and maximize the app again, the blur only gets applied to a part of the window. This bug doesn't occur on Wayland, where the application window flickers for a moment before the blur gets applied. This bug was fixed in Plasma 5.26.90 IIRC but 5.27.0 re-introduced it. *** STEPS TO REPRODUCE 1. Make sure you have blur enabled in your desktop effects. 2. Open Konsole and choose a semi-transparent theme. 3. If not maximized, maximize the app. 4. Put the app in windowed mode and maximize it again. 5. The blur isn't applied to the whole application window. OBSERVED RESULT EXPECTED RESULT SOFTWARE/OS VERSIONS Linux/KDE Plasma: EndeavourOS with the 6.1.12-arch1-1 kernel KDE Plasma Version: 5.27.0 KDE Frameworks Version: 5.103.0 Qt Version: 5.15.8 ADDITIONAL INFORMATION https://bugs.kde.org/show_bug.cgi?id=463328 This is the original bug report that got marked as solved, however, the 5.27 re-introduced the bug.
I experimented with the bug a little more and I noticed that whenever I maximized the window, it went to the top left corner, where the blur gets applied and after that it maximized. It seems like the compositor is getting wrong information about the position/size of the window.
I can't reproduce it.

I updated to 5.27.1 and it works now
Huh, weird. We made no blur related changes, thanks for the update.
The bug came back in 5.27.1-2 (wasn't there in 5.27.1-1). This is really weird.
