Unreal doesn't change appearance when changing system configuration display scaling options. Editor Texts are still quite small and don't change based on the Display Scaling %. This bug also causes the Context Menu to appear offscreen.

This was reported and tested in 4.22.3 (CL-7053642). This was reproduced in 4.23 (CL-8115738) and Main 4.24 (CL-8292946)

Steps to Reproduce

Need a Linux machine with a 4K monitor and High DPI

  1. Open the UE4 Editor and create a Blank project
  2. Observe scaling and text rendering
  3. Close the Editor and change the System Display Scaling to 200%
  4. Reopen the Editor and make sure "Enable High DPI Support" is checked.
  5. Right-click in the Content Browser or open up Editor Preferences

Results: Only certain menus have been scaled

Expected: Editor Text is readable and scaled up.
