I have gotten this error, but on pretty rare occasions -- and only after I got a new laptop and installed Linux Mint (my first time with Linux). I'm on LM20.1, with a GTX 1660 Ti.
All I've had to do is close Godot and open it again, though.
I never encountered the error on my old Windows 7 laptop (up to Godot 3.2.3), which only had an onboard graphics. With that said, @BirdaoGwra -- I always ran GLES2 on the old PC and now run GLES3 on the new one. The GTX runs circles around the poor old wheezing chip.
