UI freezes when switching to Movie Clip Editor when Blender is on second screen.
**Exact steps for others to reproduce the error**
1. New project (general)
2. Move Blender to second screen
3. Switch from "3D Viewport" to "Movie Clip Editor".
Note: This is happening in "Layout" workspace. Tested "Compositing" workspace and issue does not occur. Did not test all other workspaces.
