Hi,
I've been using this version since it has been released, without any problem, but a few days ago I tried to play with HDR and open the LUT docker and checked the "use Open color IO"; after that I'm not able to use this git of Krita. When I try to create a new document or to open any previous image, Krita stops working and Windows says that Krita encountered a problem and it will shut down. However, if I disable Open GL I can work on it. But before trying the LUT docker I was working with Open GL active.
All the previous 3.0 Beta- master are working with Open GL.
I deleted the folder and reinstalled it, but it keeps doing the same, all the time; anyone can give me some help solving this problem?
I'm on Windows 10
8 gigs of RAM and plenty of disk space.
Thanks in advance, folks.

go to .config and find the kritarc there, open it in a text editor, find Krita/Ocio/UseOcio=true and set it to Krita/Ocio/UseOcio=false.

It's crashing because your openGL support is too low, we don't know how to fix this yet, as typical checking mechanisms don't seem to evaluate the openGL specs of higher end devices properly.

Thanks a lot, Thera, but where can I find config? I've been looking everywhere in Krita and couldn't find it; could you be so kind and tell me the right way to it?!
Thanks again.
PS
Just found it. And it works.

'.config' is a hidden folder in your home folder on a linux distro. Just toggle 'show hidden folders' in Nemo or Nautilus or Dolphin, or whatever file manager you use.

Solved!
Thanks a lot, you saved my day, Thera.
