2026.13 - Local Changes diff view - Very laggy/Freezes the gui compared to 2026.12

The recent released 2026.13 Appimage suffers a issue with the local changes diff view freezes the gui,

2026.12 is completely fine.

from 2026.13, SourceGit uses Avalonia 12.0.x instead of 11.3.x.

Can you test the latest CI build from GitHub Action. I've fixed some bugs of AvaloniaEdit in my own fork.

Tried the latest CI build you linked above, still the same issue.

Try to disable the syntax highlighting first, the open SourceGit

That makes that GUI from totally freezing/hanging up, but still very laggy and not usable.

I have no idea. I can not reproduce this issue with the .deb package on my Ubuntu 25.04 (WSL2)
