Unreal “freeze” when hovering the “file type combobox” in the Import Dialog when using 2 Displays (notebook + second hdmi display) if the Displays Scales are different and you hover the combo box in the second “not main” display.
Steps to Reproduce
- In Windows Display Settings
- Set Display 1 (main) Scale to 100%
- Set Display 2 Scale to 125%
- Right-click on Unreal Editor Content Browser
- Import Assets…
- Drag the Import Dialog to Display 2
- Hover the “File Type” combobox
- Unreal will freeze
To “unfrezze” it, set both Displays to the same scale in Windows Display Settings
- It doesn’t matter which display Unreal Editor is
- If the Import Dialog is half-screen (split between the displays)
- And the “File Type” combo is split too
- Hover the split part in the Main Display Works
- Hover the split part in the Display 2 “freezes” it
Expected Result
Import Dialog File Type combobox should not freeze Unreal when using 2 Displays with different Windows Display Settings Scale
Observed Result
Unreal freezes
