And all of this will happen too if I just leave the editor up long enough. Sometimes it will just say the entire editor is not responding in the task manager after a I try to open an asset, but most often a transparent window thumbnail for the asset appears in the task bar, but the window itself never opens and cannot be viewed.

I also cannot open assets after this starts. Additionally, all the tooltips for these invisible buttons are just black boxes. They’re still clickable, but the dropdowns are invisible and the invisible buttons do not respond to clicks. When I open a level and then test it, all the menus stop working. So what happens is, I open my project (which defaults to the main menu level which has no geometry) and everything’s fine. 24 as well so I’m pretty sure it’s Windows and not Unreal 4.25 that’s the problem here. Since then, I have also tested this in 4.22. However, the problem persisted on my new hardware. These issues started in June, but I was building a new computer so I put off asking about it since I figured the problem might become moot.

I am having all kinds of problems lately, but I think they mostly have to do with Desktop Window Manager.
