[BUG] Repeated use of the fill option on small segments of a deathnote causes a crash

I was filling each individual letter on the death note I had written to create mad rainbow text, after several uses of fill the game stopped responding and I was forced to close it. Each time this has happened it has been when I was using the yellow color. Seems to be an issue specifically with using fill where the there is very little surface that is ‘filled’.

Can you force the game to update?
