Description Yaroslav Isakov 2016-08-25 12:00:52 UTC

Hello! I'm trying to run colobot under Wayland Gnome session using my onboard HD 520 , but I can only use OpenGL 2.1 driver, not OpenGL-3.3, because in EGL OpenGL is limited to 3.0, according to glewinfo and eglinfo from https://github.com/dv1/eglinfo:

OpenGL information:
    version string:  3.0 Mesa 12.0.1
    renderer string: Mesa DRI Intel(R) HD Graphics 520 (Skylake GT2)

Note that OpenGL has two context profiles: core and compatibility. Mesa does not support OpenGL for versions later than 3.0 using a compatibility profile, on any platform. 

Looking at the eglinfo source I think it uses the compatibility profile.

Furthermore, testing colobot, it tries the compatiblity profile by default, at least for the version check. Hence I think getting OpenGL 3.0 is expected behavior.

However it looks like colobot has support for the core profile and it should work with the options 

-glprofile core -glversion 3.3

Could you try if that works for you?

Yes, you were right - it is working with Mesa 17.0.6 and colobot options -glversion 4.0 -graphics gl33. Sorry for a mess (and a little delay :D)
