ID 588321 - Nuke's UI behaves incorrectly when using UI Scaling with multiple High DPI monitors

Problem summary
Nuke's UI behaves incorrectly when using UI Scaling with multiple High DPI monitors
 
This happens when the primary monitor is the right side, not the left
 
Customer reported version
nuke.14.1v4
 
Customer reported platform
rocky8
 
Steps to reproduce
 
0) Use a machine with 2 high DPI monitors, with the primary monitor on the right, and secondary on the left
 
1) Open terminal

2) Run the command: export QT_SCALE_FACTOR=2

3) Launch Nuke
 
4) Open any Nuke script
 
5) Try to use the UI, some buttons don't work, sliders always max out, panels are offset when dragging, and click the node graph causes it to pan
 
Expected behaviour
For Nuke's UI to work
 
Actual behaviour
The UI is unusable
 
Workaround
Drag the Nuke UI from the top bar, move it, then move it back. This seems to fix the issue for a while
