Apps built with Lazarus and QT5 seems not to fill the whole screen when maximized. It looks like one pixel is missing to the right, vertically, top to bottom. Clicking there gives focus to the app behind. With fresh empty projects also. Download and maximize the attached picture to see what i mean.
Ubuntu 24.04.3 LTS and 4-5 months old trunk lazarus
Is there a solution so the full screen is covered when maximized?
