Unreal Editor 5.7 UI interaction is broken on Linux for ~3 month already

Lots of good advice here. Running UE 5.7.1 on Bazzite (Nvidia Open), I launch UE like below:

alias ue571='SDL_VIDEO_DRIVER=x11 /run/media/system/hot/ue5_7_1/Engine/Binaries/Linux/UnrealEditor -windowed -ResX=3840 -ResY=2160 -nohighdpi'

I found that setting explicit resolution helps in getting crisp visual in the Editor UI and windowed mode prevents dialogues and popups from flying around. For double click, adding

[SystemSettings]
Slate.EnableTooltips=False

definitely resolves the problem. I can finally try 5.7.1 now! Been on 5.6.1, and honestly that one was easier to get going :slight_smile:
