I’ve never had a problem like this, but looking at the pictures I would guess the problem is GPU related. Based on the pictures, it looks like the OpenGL window is not being cleared correctly.
If OpenGL is not fully working, that could also be contributing to the longer loading times.
What is your GPU? Have you updated your graphics drivers recently?
Also, does the console that pops up when Godot is running show anything when loading the project and/or the editor?
Another thing that could be contributing to longer load times is other programs running in the background, especially programs that read/write lots of data from/to the hard drive (like Antivirus software, streaming software, recording software, etc). Perhaps something you have installed/updated recently is slowing things down?
It is hard to say for sure, but I would try updating your graphics drivers first and see if that fixes things, as to me it seems to be the most likely cause :smile:
