I had no problems with the Ubuntu package, but after installing Arch (Nvidia drivers installed) even the default brush is incredibly slow, so is opening a new image.
I first posted this on the Arch forums but so far no one replied.

Few things to check on linux:
1. settings->configure Krita->Display. Check if OpenGL is on, and whether setting the filtering to 'trilinear' improves things. 2. Check if you didn't accidentally picked 16bit float. 3. Check if in the tool options you didn't accidentally set the brush smoothing to 'stablizer'. |

OpenGL was on by default and turning it off actually sped things up, except I had the good old jittery panning back.
Ahh. I was simply an idiot and forgot that I pushed the resolution a bit too high (A4 600 dpi) for the GPU. I think it was faster without OpenGL because it had access to more RAM. *facepalm* |

Welp welp welp.... now even 1024x768 is lagging
So does 300 dpi A/4, which I clearly remember having worked before.... |

yea, I am thinking it's something completely different. In the status bar, you can click the resolution icon, and it tells you what krita is doing in terms of memory consumption.
Also, please check the list of things I pointed out. |

I've checked the first two, OpenGL was on and I was using 8bit integers. The third I couldn't find, but I was using the default circle brushes, without any changes.
I would check it, but now I have removed Krita to try the Git version from the AUR and it's still building. |

yes, but did setting the filtering to trilinear help things?
The stablizer is in the tool-options docker. Anyway, let's hope the git version improves things. |

Oh, sorry, my eyes skipped that. Yes, I've played around with that setting too.
I think trilinear was set by default, not sure. Anyways, I switched it as low as nearest neighbor and it changed nothing or at least nothing visible. To be precise with "lag": only image operations (creating, panning, zomming, painting, etc) are slow, the menu itself is fine. Building is almost done, I'll put the results up soon. It failed, because the Krita-Plugins dependency could not be satisfied. .__. I'll try a few others to see if the results change. |

I couldn't install any of the other packages, so I reinstalled the default one with Pacman and ran Krita from command line.
Here is the output. There seem to be a fair amount of warnings at first glance.
Output of glxnfo

Ah, ok, I figured it out, GLFW was not installed.
