Hello, I am writing about a unwanted window behavior that I encounter on KDE using Debian 12. When Firefox is half- or quarter-tiled to the screen, the tiling is undone each you click on the upper edge of the window. Steps to reproduce: 1. Tile the Firefox window to one half of the screen 2. Hover the mouse over the upper edge of the window. The resize vertically icon appears. 3. Click to resize the window Encountered behavior: The window goes back to the size and position it was before tiling the window. Expected behavior: The window remains in place. One additional behavior I discovered while writing this message is that: If you maintain the click and hover the mouse down, the window (which jumped to its previous size and position) returns to the tiled position and follows the resize movement (as intended). I usually intend to switch to another tab when I trigger this behavior. I hover my mouse all the way up on my screen on (well, actually above), the tab I want to navigate to and click. While I agree that it takes is not to hover the mouse all the way up, it is very irritating that window jumps to another position so easily. Other applications on KDE do not show this behavior. Therefore I assume this behavior is specific to Firefox. Furthermore when the window is maximized, this behavior doesn't occur (because these is no resize action available in that case). About my System: Debian 12 KDE Plasma Version: 5.27.5 KDE Frameworks Version: 5.103.0 Qt Version: 5.51.8 Kernel Version: 6.1.0-25-amd64 Firefox: 130.0.1 (Installed using Flatpak) Is this a behavior known to you? Kind regards, Nathan van Schoote
