--- Short description of error ---
I start painting and right after 1st click Blender stuck on this "picture" forever (see the attachment)
--- Steps for others to reproduce the error (preferably based on attached .blend file) ---
Sorry, I can't give you a .blend I think the reason is the dependency cycle which actually isn't involved in that
painting. But something tells me it's the reason.
If I append a part that must be paint on to a fresh file - painting works fine.
BUT baking textures with these dep. cycles works without problems!
Please, re-arrange if I'm wrong with the category.
Description
Event Timeline
The dependency cycle warning is unrelated. There are however multiple warnings about Blender running out of memory, it's using about 1GB of memory already and there's no more memory left to allocate more. I don't know how much RAM you have on your computer but because it's windows 32 bit the amount available is always going to be limited.
It may be that Blender is using an unreasonably large amount of memory here, but it's impossible to tell without a .blend file. So all I can suggest is to get more memory or simplify the .blend file and use lower resolution images.
Also you could reduce the number of undo steps to save memory. It's also possible to print some statistics about memory to the console with spacebar search operator > memory statistics, it gives some idea of what is using the memory.
Can't do much here without more information, but I'm pretty sure this is just a regular case of running out of memory, which we unfortunately don't handle gracefully in Blender yet. So closing report.
Sorry for not answering.
Yes, most probably I've set too much textures in that .blend and it's about this.
