I just came to report that, on Linux Mint + Xfce + Compton, swapping to the Fusion style makes the maximize button come bac. The button also works as expected. Does this bug come from the theming system?

This was reported for a very old release. Can you confirm that this still exist in the latest release 25.04?
I was on the latest release when I said that. I am still still on the latest release.
That is probably happening as there is just not enough space available to fit the window onto the screen. The behavior of the maximize buttons is system-dependent (hidden, not working, greyed out, ...) unrelated to Kdenlive. I'm not aware of a global minimal size (width or height) restriction for Kdenlive. I think the minimal window size is calculated based on all the panels/widget visible in Kdenlive. Try to use a different layout. The default "editing" layout which is shown if you haven't customized your layout needs quite a bit of vertical space (I cannot shrink it too much). Try clicking on the "Effects" layout (this one needs less space, so maybe the maximize button works in this scenario). You can also create your custom layout which better works with such a small screen. Can you give this a try and let us know?
Created attachment 182068 [details] screencast showing behaviour of gnome shell / kdenlive on resolution 1366x768 I tried to reproduce this on a nested gnome environment with the reported resolution and can confirm similar behavior as reported. The default/editing layout does not fit but the effects or audio layout does (and hence the maximize button works).

I have returned with a test! My results were the same baloii's; the audio layout fits, and the maximize button came back.
I can confirm that changing the layout restores the maximise button. It's strange that, with no changes made, the button remains on Plasma Desktop with the same display scaling, yet disappears on Linux Mint.
