SUMMARY STEPS TO REPRODUCE 1. Switch to Wayland; 2. Try to maximize the window. OBSERVED RESULT The window won't maximize. EXPECTED RESULT SOFTWARE/OS VERSIONS Operating System: KDE neon 5.22 KDE Plasma Version: 5.22.0 KDE Frameworks Version: 5.82.0 Qt Version: 5.15.3 Kernel Version: 5.4.0-74-generic (64-bit) Graphics Platform: Wayland Processors: 8 × Intel® Core™ i5-8265U CPU @ 1.60GHz Memory: 15,5 GiB of RAM Graphics Processor: Mesa Intel® UHD Graphics 620 ADDITIONAL INFORMATION The Settings window was maximized when I was on X.
Ops, I meant "unmaximize"!
1. Do you have the "Maximizing" window placement mode set, by any chance? 2. What happens if yo manually drag the window somewhere else, resize it to be as small as it can be, maximize it, and then un-maximize it?
1. No 2. I can't resize the window. If I press "restore", nothing happens
I use the "centered" window placement. Also, I don't have any window rules for Settings.
Ok. So can you drag the window somewhere else and resize it by the corners or edges?
Yes, I can do this. Also, after doing it, I can restore and maximize the window again. I changed the window placement back to minimal overlapping, but it didn't work.
Right. So the bug is that when you maximize a window on wayland and then quit and re-launch the app, the window is opened with the *geometry* of a maximized window, but not the *state* so clicking the maximize and un-maximize buttons don't seem to do anything because the maximized and non-maximized sizes are identical. *** This bug has been marked as a duplicate of bug 437089 ***
I probably mis-triaged this bug. That said, I cannot reproduce the specific issue described here. Instead I experience a different one: when I maximize System Settings, quit it, and re-launch it, it doesn't open in the maximized state. I've filed Bug 478443 for that.
