Unreal used to work fine, but now I can’t open any of the windows up top like File Edit Window Tools Build Platforms Select or Actor. I can’t even close Blueprints. Sometimes after pressing them multiple times they will stay open, but then go back to not working. I already uninstalled and reinsta…

Hey, try disabling any overlays you possibly have enabled for Unreal like Discord Overlay or NVIDIA App overlay. That worked for me, hope it works for you too.

Same Issue.. For some disabling Discord overlay and other overlay fixed it but not for me. You wouldn’t happen to have an ultra-wide Monitor?

Hello folks! I was debugging things around this since friday. What helped is setting this console variable WindowsApplication.UseWorkerThreadForRawInput 0 See details here https://github.com/EpicGames/UnrealEngine/commit/b1a6f9bb44d20d6bb0498540359b9ea87e2dbbb4#diff-967a8b052ddc8562232809da4bb4dcb…

I couldn’t move the window or close it, and clicks inside the window were ignored. Setting UseWorker…

My editor dropdown menus visually duplicate parts of main editor window while the buttons are functionally present. Windows 10, UE 5.7.1, no Discord app, disabled NVIDIA overlay, UseWorkerThreadForRawInput=False set. None of this has helped. This has completely halted my 5.7 project.

Follow this thread, this is exactly what is happening to me every dropmenu duplicates parts of the main editor

“every dropmenu duplicates parts of the main editor” Solved it by resetting my Nvidia control panel settings. It was either forced Vsync or something else. Resetting and enabling the needed settings one-by-one and testing UE editor is the way. EDiT: Nvidia, Steam and other overlays enabled and all…
