I could be wrong, but I don't think it's the render cache that causes this problem. The viewport of the node editor in the materials room is not responding. After I saved my texture in Krita, the previous version of it is physical gone, overwritten with the new one. The only thing that stays the same is the name of that file.

Thanks for the advice in regards to the tif file format. Krita can handle tif and psd files alike. It should be no problem to check on your notion. If the file format is causing this behavior, I will let you know.

Thanks so far. I'll check out the suggested solutions and see if it works out.
