OpenGL error: glValidateProgramPipeline: pipeline 1 does not meet strict OpenGL ES 3.1 requirements and may not be portable across desktop hardware

Hi, Just compiled REGoth-bs on my Fedora 32 (x64) PC.

I run REGoth from the build folder with:

LD_LIBRARY_PATH=lib ./bin/REGoth /mnt/omega/wine/gothic2/drive_c/GOG\ Games/Gothic\ 2\ Gold/Data

But it crashes with the following error. Any help would be exellent!
