I get a new crash, unfortunately pretty basic (again) but at least it's not in the same place, so here's hoping it comes from somewhere else (and can be fixed...maybe it's even because of unsupported functions, who knows?)
Here's the crashlog (excerpt)

and here's the file where it complains (I know that it still says ResidualVM, they didn't change it yet)
https://github.com/scummvm/scummvm/blo ... aphics/opengl/context.cpp
I can see two things:
1) It's again the glContext i got a crash from earlier (but this crashlog was done *with* the fix already in place, so i guess it's close, but not yet there)
2) The first affected line points to something related to FBO (which i know is not supported in OpenGL, but is maybe the reason why it bombs?)
If anyone has any hints, workarounds i could try or other help, please shout
