Weird color picker behaviour

[KDouble48]

Godot version

4.0.rc5.official

System information

Windows 10, Vulkan, RTX2080 (528.49)

Issue description

1. When using the colorpicker, I can't undo the change. When trying to close without saving, the editor freezes and I have to close it with the task manager.

2. When using the color picker, the top and bottom of my screen turns black. Nvidia GeForceExperience detects a Game (also works with it disabled). Also the whole screen turns black when I move the editor to my second display and try to open the color picker.
   
   If I move the editor back to my first display, it zooms into the editor.
   
   The console mentions wrong pixels sizes. Propably referencing the different resolutions of the displays causing this issue.
