Raspberry-Crocodile commented 2 years ago

Version

1.86.4

What happened?

Applications (e.g. example from this repository - ./gradlew :example:run) with enabled ImGuiConfigFlags.ViewportsEnable fails if you have two displays with different UI scaling configured throught Windows 11 settings (e.g. 100% and 200%, 125% and 150% etc)

Reproduction

Prerequisites:
-Windows 11 Pro (21H2 v.22000.527) (have no idea is it reproducible on Windows 10 or not) -Two displays with different UI scaling (e.g. 100% and 200%, 125% and 100% etc) My monitors have different resolutions (UHD and FHD), but application runs fine while you have same (does not matter which one 100% or 175%) scaling on both monitors -Copy of this repository of version 1.86.4

Steps:

  1. execute ./gradlew :example:run
