Mousepad turning "black and blue" mid-text
I've been using Mousepad on XFCE for years and I'm very happy with it! Today, I've encountered a strange thing (on Xubuntu 20.04, Mousepad v0.4.2):
I've opened a textfile generated by ffmpeg's "ffprobe" utility - and suddenly parts of the text turned to background color black, font-color dark-blue (see screenshot):
Everything else (editing, etc) seems to function normally, but some parts of it suddenly are displayed "dark". When scrolling through the text, the coloring seems to switch/jump to different lines/parts/blocks of the file.
The only thing "out of the ordinary" could be that the textfile is "rather large": ~13MiB (12682589 Bytes).
I was curious about what was causing this, and I'm pretty sure it looks like unintended behavior.
There the issue report
Thanks for any information on this. Thank you very much in advance.
