Description JayJay 2013-05-03 15:33:03 UTC
Krita uses up all physical and swap memory if too many brushes are added in brushes folder.
This happens even when open file dialog is visible and no file is loaded. With less brushes, less ram is used.

Reproducible: Always

Steps to Reproduce:
1. Add many abr files in brushes folder
2. Start Krita
3. The used memory should surge
Actual Results:  
Both swap and physical memory maxes out

Expected Results:  
Krita should be able to deal with a big no. of resources and memory shouldnt max out.

Gimp deals with the same no. of brushes fine. I am not sure if this is even a bug.

Thanks for the report. We really need to have two-phase loading for brushes and some kind of max number of brushes in memory.

Pushed by rempt into branch 'master'.

Drop the full brush image after loading it to save memory

When we need it for painting, we can reload it.
