Description Matt 2015-09-08 00:19:50 UTC
Despite working fine a few days ago, rotating and zooming in and out is now incredibly slow and stuttery. This happened once before when I was using windows 8.1, it was solved by installing the latest beta version and hasn't been a problem until now. Currently I'm using windows 10 and the problem popped up again, installing a new version didn't help. It is sometimes less severe when I zoom far out, but otherwise it makes it more or less impossible to use krita.

I've tried reinstalling, restarting my computer and installing new graphics card drivers. 

Thanks

check the ogl settings under:

settings->configure Krita->display.

If OpenGL is turned off, turn it on again, and if it's on, set the filtering to trilinear instead of high quality.

It might be a windows 10/opengl problem. Could you please check Wolthera's suggestions and tell us if that made a difference?

Turning on openGL worked perfectly, totally back to normal! Thanks so much!
