2947344eda Compat: Check for successful GLEW initialisation fails on my PC / Trixie 
I observed same strange behaviour already last year on my »Video Output« talk.
The return value indicates an unkown error, but the subsequent usage seemingly works...

On my Laptop, I don not see this error; it might be due to the very old graphics card on my PC...
