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

[Ares9323]

@Ares9323

Not only on Linux, I’m on windows 11 and I’m not able to click buttons, drag windows and do most of the operations (and I’m in the preview build, not in the source build)

I hope this gets addressed before the stable release because I can’t find anything about this!

(It’s happening only on some projects, e.g. the NDisplay template)

Still happening on the non-preview release of UE 5.7.0, less often but with many other issues:

• Can’t click to switch to Editor Settings/Project Settings menus docked in the toolbar
• Can’t click Buttons in popup menus
• Can’t focus some windows
• Cant’ open assets from content browser
• Cant’ drag windows

Keyboard shortcut seem to work, the issue is with the mouse only, if I try to record the issue with ShareX and I press Shift+PrintScr it starts to function again so here’s a video recorded with my phone:

Edit: The Windows issue was completely unrelated to the Linux one, i found a temporary solution here: Unreal 5.7 Ui not working? - #3 by ILunin
