CapCut Tip:
Here's the fix: find the capcut exe file ➜ choose properties ➜ compatibility ➜ enable run at 640 x 480 resolution ➜ change high DPI settings ➜ override high DPI scaling behavior ➜ system.
Now, Capcut UI will run at a lower resolution when launched. The screen will automatically revert back to the default screen resolution when Capcut loses focus.
