Issue description

When i open MCreator, appears the loading screen, but sometimes happens that then appears a white screen in MCreator window (as you can se in the screenshot below), but the program still working, it doesn't crash. I try to restart MCreator but nothing. After a few minutes, evrything goes back to normal. I don't know how to fix this. I am using 2020.2 version of MCreator.

Here it is! (For privacy i censored my user folder name and the time of all the process).

Ok i solved the problem. When it happens, you have to extend to full screen the MCreator's window, and the screen will appear. 

I thought i had resolved the problem, but it still happens. Help me, please?

Ok i finally solved the problem. In the options, while you activate the 2d OpenGL acceleration, UI doesn't load, so go to <user home>/.mcreator/preferences then open the file by a noteblock, then write this <use2DAcceleration": false> (before was <"use2DAcceleration": true>). This is a bug wich i hope will be fixed.
