On this version the canvas rotation is very laggy. The Panning and zooming are still smooth.
With OpenGL disable everything is laggy, but with it enable only rotation is still laggy.
I have Intel graphics and Nvidia GTX 650ti.
On previous versions canvas rotation were smooth too.

Reproducible: Always

Steps to Reproduce:
1.Open a document
2.Rotate the canvas
3.

Actual Results:  
Laggy canvas rotation

Expected Results:  
Smooth rotation

I tried using only Intel graphics, and only Nvidia, but the result is the same.

Hi,

Thanks for your report, but I'm sorry, I cannot reproduce this issue. Performance issues can differ a lot from system to system, and OS updates can cause problems in between. Please try the latest 3.1 beta (http://download.kde.org/unstable/krita/3.0.91/) and make sure your display drivers are up to date.

There just isn't anything more that I can do here. We had to rewrite most of the opengl code since the 3.0.1 alpha for the new beta. It might be better for you, or the same... But we cannot fix something we cannot reproduce.
