I have 2 monitors, one FullHD with scaling 100%, one 4K with scaling 175%.
When I close and then launch Caprine again on FullHD display, it reopens with the same size of window, which is fine.
However, when I do this on 4K (175% scaled) display, it reopens much bigger - if it had half of the width and half of the length of display before closing, it takes almost all of the screen after reopening. I usually have Caprine on like 3/4 of my screen, which results in window that is bigger than my screen, so I have to manually resize it (make it smaller).
My primary monitor is the FullHD one.

Note: this bug is also present in Skype app and Element (for Matrix) app. Apps like Messenger Desktop or Spotify doesn't have this bug.

Also, when opening the dialog for choosing file to upload, this dialog is too small on 4K screen. For example, Messenger desktop has this dialog properly scaled (but has another bug, which is gradually decreasing height of this dialog :D ). I guess it might have the same/similar cause.
