Hello,

Sorry to bother with this silly question, but I'm just wondering if someone could help me get the OpenGL canvas working properly.

I'm not sure of the all the exact information I could provide that would be helpful so I'll provide what I can.
I'm currently on Fedora 22 with Gnome 3.16.2
Gallium 0.4 on NVC1 for graphics drivers with an nvidia 630m
OpenGL version 3.3 under Mesa 10.6.3
Qt version 4.8.6
Krita version 2.9.5

The issue with the openGL canvas is a great deal of lag. I should note that for most things the normal canvas works fine with good performance but wrap around mode is not available as well as the rulers lag and cause a lot of artifacts in the normal canvas.

Well, there are two options to get the opengl canvas working properly, and neither is really practicable: the first would be to rewrite Krita's opengl code fit within the limitations of the driver, the second to fix the driver to properly support Krita. That sucks, but _if_ you can build Krita yourself, you could try to build the frameworks branch, which has a largely rewritten opengl canvas (we had to do that for the Qt5 port...) I'd be very interested in reports...

I currently can't access the git repository to check which branch it is exactly you speak off (502 error when trying to access). But I'd be more than glad to attempt building krita and submitting bug reports on that build.

In regards to building krita, I've been looking for a definitive list of dependencies but not been successful finding one. David's post doesn't seem to list everything and vice versa with the kde wiki post on building calligra. It's possible I missed something when looking but should I just go off both in conjunction or just accept the calligra build command for fedora and trust that it will install everything (minus vc) on it's own?

Thank you for the swift response!
