Pierre,

it. The branch with the changes is this one:

Your configuration is similar to mine. I don't see how video driver could
interact with overview widget.

Are you comfortable debugging krita? Could you try running krita in a debugger.
Build with debug information and run 
"gdb krita"

When krita starts freezing, you can break in debugger and give "bt" command and
then "c" to continue. Repeat a few times while krita is freezing. If you see
that debugger often stops in the same places, could you post backtrace from bt
command. It may point to the place where code is looping.

I cannot reproduce it on my Linux system. I created a 3000x3000px image, 16 bit
(int) RGB color. 5 layers and drew for a while, but the system is running fine.

Could you please provide more information:
1. What's the revision you are using? You can run git rev-parse HEAD to get it.
2. Which compiler (gcc or clang)?
3. What version of Qt are you using? 
4. What linux distro? 
5. Is it possible that you are running low on memory? Does "top" command show
enough free memory and no swap is used. How much memory is krita using?
6. If you "dock" the overview docker, is krita still freezing?
7. If you close the overview docker, is it freezing?
