### Godot version

Master (0ddd9c3e8f9088fa139e25b2903289d727073e12)

### System information

PopOS 22.04 - Intel integrated graphics - all backends

### Issue description

When there are popup windows in the editor, I cannot click on the "Confirm"/"Cancel" type buttons at the button. 

I have the issue both in the project manager (importing projects I can click on files etc. but cannot click "open") and when running the editor (cannot click "Save&Quit" etc.)

Sometimes the editor correctly highlights the buttons and I can use the arrow keys to navigate the buttons and "enter" to confirm my selection.

_I can navigate the editor closing dialogue with tab/arrow keys_
