I dont’t know this is a bug or there is some problem in Linux. The same option doesn’t have problem in Windows.

This method works perfect on UE5.3. Hole can help you.

OS: Arch

Another option to change the UI Scale is under Tools/Debug/WidgetReflector
There you can change the Application Scale to your desired size (I changed mine from 1 to 0.7)

Ok even better yet, go to your Editor Preferences and look under General/Appearance and change the Application Scale there so the settings will be saved after restarting the Editor:

Use the -nohighdpi argument on the Unreal Editor launcher is the only good solution so far.

“Editor Preferences > General > Appearance > Enable High DPI Support”

Always fails to apply.
