Hi Krita team,

first: thanks for the wonderful program! it's simply amazing!

I had a problem on a MacBook Pro with an AMD gpu where Krita would not enable Canvas Graphics Acceleration in the preferences/Display.

This seems to have something to do with AMD gpu, and I still can't figure out what exactly, but meanwhile I found a simple workaround that can make krita run on the Intel gpu:

Add this key to the app's Info.plist:

NSSupportsAutomaticGraphicsSwitching

With a boolean value of YES

After this change, run the app again and OpenGL is enabled (and for some reason uses Intel gpu - so it ain't switching as the key is suggesting)

hope this helps,
nesa

You probably will run into trouble saving to PNG or JPG or similar file formats; AMD/ATI cards block Krita when saving to single-layer files if canvas acceleration is enabled. See https://bugs.kde.org/show_bug.cgi?id=369014

thanks for the warning.

I've just run krita freshly compiled from yesterday's master and AMD card seems not to be disabled - yeey.
Canvas Graphics Acceleration is on and working.
I've done a quick test of saving & rewriting png/jpeg files and didn't experience any issue yet(no crashes and the pics are saved properly).

so perhaps you guys already fixed this:)

cheers,

Yes, it's fixed in master -- I guess I forgot to mention that here, because I also answered a bug report about this problem this week... Note that git master currently is under extremely heavy development. If you need to use text or vector graphics, be careful. And also be careful to save regularly, and _check the results_, because we completely rewrote the saving system!
