4.16 - missing spaces between characters in dialog boxes

some dialog boxes, like opening maps, generating code, compiling, etc do not have spacing between characters. Unreal is run with a flag: -enablehighdpi

In 4.15 is was looking fine, so it is regression.

Hey Flash7,

I was unable to reproduce your issue on our end. I have a couple of questions to help narrow down your issue.

  1. Are you using a custom font within the engine?
  2. Where are you enabling high dpi?


  1. no, font is standard
  2. “C:\Program Files\Epic Games\UE_4.16\Engine\Binaries\Win64\UE4Editor.exe” -enablehighdpi

Opening a new level in the editor

I use 4K monitor

I checked also by launching 4.16 without -enablehighdpi - fonts are OK. But with -enablehighdpi fonts are condensed.
In 4.15 everything was good.

Does your issue occur for you on a monitor that is not 4k?

No, it is only on 4k monitor. On another monitor it looks all right, see attachment.


. The same in 4K:

4.16.0.p3 → still no spaces

I have another post for the launcher: Launcher on 4k display - Getting Started - Unreal Engine Forums

I can confirm this bug also exists in newest “Epic Games Launcher”, I just accidently added the -enablehighdpi to the launcher, and found that the launcher did support high dpi. but the fonts are rendered without correct space.

Also the exact same problem exists in UE4Editor.exe
