I tried to update to 0.44 but the problem still exists

[DreamMaoMao]

The problem disappeared after I cleaned up the system, including uninstalling git, cleaning up environment variables, uninstalling some applications, re-installing git with winget, and restarting the system. I don't know which part of it is responsible, but since I haven't made any changes to lazygit, it shouldn't be a problem with lazygit.

For what it's worth I've started seeing this too. It might be correlated with installing Windows 24H2: it happened around that time. On opening a new Windows Terminal it's fine for a bit, then starts to really crawl. Closing and re-opening Windows Terminal fixes it. Other applications running in the terminal, such as vim, don't have this issue.

[canton7]

Interestingly, changing the anti-aliasing mode in Terminal (Settings - Defaults - Additional Settings - Advanced - Text antialiasing) also fixes it, at least temporarily. Doesn't matter what you change it to, just the act of changing it has an effect.
