SUMMARY There is always a 1px border on right and left sides of a window. It looks like "disable borders" is really "set borders to an invisible 1px". This prevents from selecting options from sidebars in some programs if you move your mouse to the edge of your screen. Really irritating. STEPS TO REPRODUCE 1. Settings -> Look -> Program look -> Windows look -> Disable borders 2. Install any program that has a sidebar (Thunderbird should be fine). 3. Move your cursor to the edge of screen, where there is a button on the sidebar. 4. Click. 5. Move your cursor one pixel away from the edge of screen. 6. Click. OBSERVED RESULT 4 - Nothing happens 6 - Button is activated EXPECTED RESULT 4 - Button is activated 6 - Button is activated SOFTWARE/OS VERSIONS Operating System: Debian GNU/Linux KDE Plasma Version: 5.17.5 KDE Frameworks Version: 5.70.0 Qt Version: 5.14.2 Kernel Version: 5.7.0-8.3-liquorix-amd64 OS Type: 64-bit Processors: 4 × Intel® Core™ i5-2400 CPU @ 3.10GHz Memory: 7,7 GiB
I should also include "2,5" step, "Launch the program and maximize it".
Probably a duplicate of bug 387775. Please confirm if it only affects the left edge.
