I’m using Fedora 42 Workstation (Gnome) with a Wayland session. Unreal Engine is apparently running via XWayland.
So there I was trying to create a Blueprint from my C++ class. I get an empty dialog box for “Pick A Parent Class” and need to start over. Workaround: go to the C++ classes in the Content Browser, right click from the one I want and select Create a Blueprint…
I need to do this for Gameplay Effects, as well. (I’m guessing that’s an internal C++ class.. the same work around work there, I just need to look in C++ classes in Plugins)
The thing I cannot get around is this: I tried to migrate some assets and evidently something is wrong with an asset audit, and it wants to tell me in a pop-up message. Unfortunately the Message is invisible and I need to tear it all down with “ps -ef | grep Unreal” and kill -9 my way through the Unreal Editor processes.
It also similarly hangs if I click on a color to bring up the Color Picker dialog.
None of this had been a problem in 5.4.x.
UPDATE:
I logged out of the default session and tried Gnome on Xorg. That solved the Pick Parent Class and Color Picker issues. (My build did not handle Wayland quite right, it would seem. Good to know.)
I have not hit the Asset Audit message yet, because of course not, but I am thinking I can work around a lot of stuff just by using the old Xorg session while I still can.
