Confirm or reject my suspicions about the massive default window sizes
My laptop has a display resolution of 1366x768. Every now and then, I'll encounter a window whose default height is over 768 and thus won't fit entirely within my screen. The GTK file picker comes to mind, though it is resizable without much fuss. But then there are those that cannot be resized and being unable to move the titlebar further up, I am forced to use Alt+F7 to see what's at the bottom.
I suspect that many programs today are designed to work comfortably on higher resolution displays, but not really tested on smaller ones. Understandably, developers only have so much time and 1366x768 is getting long in the tooth. Just wanted to put this out there since nobody seems to be talking about it.
If you use Xfce, you can make your display bigger than its maximum resolution by using scale in display settings. Chose "Custom" and set it to 0.5/below. Don't set it to above 1 because it will make your display smaller and don't set it too low because it will make your display blurry. If you encounter an issue when play game, you must revert your setting.
You can do this too with xrandr but i don't know if this will work in desktop environment. You may try it if you want. I never try this with wayland.
