here again, I edited a scene, looks identical to me

Some questions I have:

• Which version do you use?
• What operating system are you on?
• Have you configured to use any theming with Qt?

[thob]

• Manuskript v0.15.0
• Pop OS 22.04
• yes, I had Adwaita dark theme

Also, I observed that LT consumes a lot of CPU for each checking a misspelled word

[TheJackiMonster]

Okay, I recommend to disable the theme. Qt themes can actually cause segmentation faults (crashes) inside of Qt itself. We can't really fix this in any way on application level. If you can still reproduce it, let me know.

LT processes more text than theoretically necessary every time you make changes to your files. That's why it's this heavy on the CPU. There are ideas how to improve that but they still need to be implemented since it's not trivial. If it's too bad in practice (increasing loading times for example of your files), I recommend switching to a different spellchecker.
