SUMMARY
Krita slows down and eventually crashes after fast repeated strokes with
textured brush. This does NOT happen in nightly
krita-5.1.0-prealpha-c2e53df-x86_64 from 31 August.
STEPS TO REPRODUCE
1. Select any brush preset with pattern assigned (for example c) Pencil-3 Large
4B)
2. Make many short quick strokes like when crosshatching or even faster.
OBSERVED RESULT
After varied number of strokes (over a hundred) Krita will pause before
rendering each stroke, this pause will grow longer and Krita will soon close.
EXPECTED RESULT
None of the above happens.
It seem Krita spams exception on every stroke into log, i've shortened the log
as it was several megabytes of the same line.
