Linux, mouse cursor is 'afraid' of clickable areas

have a project that runs fine under Win10 and MacOS.

But in the Linux version (crosscompile in Win10) when run a second time under Linux, the mouse cursor “jumps down” (right under the object) when it touches objects in the ‘game’ which are ‘mouse sensitive’, i.e. objects that can be clicked, so that they can’t be clicked any more.

It’s just like if the cursor is now afraid of the areas…

First run runs fine. subsequent runs have this problem. When deletetin the program folder and unzipping it once more, it works again for one time.

already tested on other PC with different graphics card
