Hello all, first and foremost I´d like to thank you all for this amazing software, it´s the only sofware that I ever used that I feel like freehand drawing with regular paper and pen. Also I really like the mentality behind it and as soon as possible I hope to start to contribue to it. Now, the bug I found is that after installing beta 2 the zoon and rotate tool became very slow, very lagging to the point that I can´t use it, so I tried to go back to beta 1 and the problem is still there. What can I do or what can be done? well this is it. By the way when I had beta 1 before beta 2 all was fine, no lag at all. .... help!!!!

houdy, it´s solved. it seems that when I installed beta 2 it unchecked my display settings, so it was just a matter to check it back.
Zooming and rotating is directly related to the graphics card (which is not used in just painting).
Go to settings > configure krita > Display > Canvas Acceleration and check if you have it on, and what is your picked renderer.
I don’t know which one you used before, but I suppose it got switched off with updating krita and now it stays like this.
