Dear Maintainer, since the change from debian/bookworm to debian/trixie I discovered a little annoying issue. The problem is, that switching an application from fullscreen to windowed screen is not working properly. An example: Do the followiing with firefox or kmail (or some other app): - start firefox - press F11 for fullscreen or run a video with fullscreen and pre - press F11 again (to switch back to windowed mode) You will see, that the upper bar does no more fit into the screen and is no more clickable. To close firefox (or kmail whatever) you have to use ALT+F4. I suppose, this is because my screen resolution is 16:9 and not 16:10. Sadly my desktop computer monitor is also 16:9, so I can not test it. Thus this reason is just a suggestion, as it looks fpr me, the screen is not turning back to 16:9 but 16:10. I am running X11 as wayland is not usable for me (slow and unstable), and for testing purposes it handles windows in a fully other way than X11. It would be nice, if that could be fixed before you completely switch to wayland. Thanks for reading and your help. Best regards Hans
