Hi, I have surface pro 4 i7 16gb ram - Windows 10

Krita has recently been very slow to respond and the brushes have been laggy. I had Krita all set up and running great then something changed. I dont know what verison I had but the splash screen was a person laying on their back holding up a cat. The splash screen changed to a blue mouse and I think thats when all the problems started happening.

Does anyone know which version I had and why would it change?

I was able to get 2.9 to run smoothly but it doesn't have all the custom brushed I made.

I installed Krita and was working with it for about 2 months. Then I found out out about Gemini so I wanted to try that. Gemini required Steam. I installed steam which could maybe have caused Krita desktop to update? I did not like Gemini. When Krita desktop got all screwy I uninstalled Steam. No help. I tried a bunch of teaks I found online - turning off brush smoothing - changing performance settings - turning off open gl - downloaded surface drivers and wintab. None of that made a difference. I also tried reinstalling Krita3.1 and 3.1.1 but neither would work like it did when I had the splash screen of the person on their back with the cat. Am I crazy?

Hi,

Krita Gemini is an older version of Krita for 2:1 pc's (well, like the surface), but it's really hard to keep it up to date because of technical challenges. I would recommend uninstalling any version of Krita you might have and the go and find the kritarc file(s) in your %APPDATA% directory, and rename that to kritarc.bak. Then try the latest stable release, and see if that is faster. We do have a bug report from someone who says that at a certain point removing or renaming the settings helps with some performance issues, but I haven't had time to dig in yet.

Thanks I am going to try that. One thing I found that fixes it. I downloaded the ziped version and ran Krita without installing it. It worked much better. I am assuming there are files left behind after uninstalling Krita that are messing with the new install.
