Created attachment 142962 [details] From Krita's error dialogue SUMMARY After adding a pattern in a brush (ink 3 g-pen in my case), changing to the brush became too slow. STEPS TO REPRODUCE (might) 1. add a pattern to a pen 2. tweaked brush setting (I checked rotation etc) 3. overwrote brush OBSERVED RESULT Too slow only to open the ten brushes' dialog of the pen when clicking 'Edit brush setting' in the tool bar or typing Ctrl+Alt+3 (in my case). EXPECTED RESULT SOFTWARE/OS VERSIONS Windows: windows10 21H1 macOS: Linux/KDE Plasma: (available in About System) KDE Plasma Version: KDE Frameworks Version: Qt Version: ADDITIONAL INFORMATION
Self reply After posting this error, I checked Krita's configure files.
following above. I found out a funny record in C:\Users\<user_name>\AppData\Roaming\krita\kis_brushes.blacklist. The pattern name I added was being registered as ????.png. As I used 'UTF-8'(kanji).png, Krita seemed not to be able to process it. I delete it and re-register the pattern as <ascii>.png then deleted files relevant to this bug. Now Krita looks like running well. I hope to be able to use UTF-8 code.
Krita 5 no longer uses the blacklist file.
