Original GitHub issue: https://github.com/debauchee/barrier/issues/631

Operating Systems

Server: doesn't matter
Client: Windows 10 version 1903 (OS Build 18362.778)

Barrier Version

2.3.2-snapshot-210c2b70

Steps to reproduce bug

Have 2 or more monitors.
In Windows settings, under System -> Display -> Scale and layout, set the scaling value for both monitors to different values.
Start Barrier and observe the UI as you move the application window between monitors.

See this screenshot for example:

Also, on high DPI monitors the version string in the About dialog is cut off. The easy fix would be to allow resizing of the about window.

Other info

Is there a way to work around it? Yes, if you set the scaling behavior override to System in the barrier.exe properties dialog under Compatibility, the scale is OK. However, this also makes the application blurry as Windows then simple scales up the bitmap.
Does this bug prevent you from using Barrier entirely? No

This bug is caused by issues in the DPI awareness of the application. Here is the relevant QT documentation.
