Regression: lag when switching tabs since verison 2099

[eugenesvk]

Version info

• OS: macOS 13.4
• Build: 2099

Description

Switching between tabs (location/commit/files) lags when done via a keyboard shortcut since 2099 - it adds a blue highlight border, which I think is related since when you switch with a mouse there is no such border and no lag (and there was no such border before 2099 when using keyboard shortctus). So whatever is represented by this blue border is blocking/expensive

Steps to reproduce

Steps to reproduce the behavior:

1. Open repository
2. Press a shortcut to activate the Commits tab
3. Press a shortcut to activate the Files tab
4. repeat steps 2-3 in quick succession
5. Observe the blue border lag

Expected behavior

No lag in switching, just like before

G'day @eugenesvk,

Thanks for reaching out and sorry to hear you're experiencing this performance issue.

Can you confirm if you have hardware acceleration enabled? This can be found in the Sublime Merge preferences page (accessible via the application menu under Settings... > Preferences... > Advanced > Hardware Acceleration).

Kind regards,
- Dylan from Sublime HQ
