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

Yes, Enable - OpenGL

Hi @eugenesvk,

Can you confirm if this is still affecting you on the latest version of Sublime Merge?

Kind regards, - Dylan

[eugenesvk]

yes

Hi @eugenesvk,

Apologies for the delay getting this fixed - I've been unable to reproduce the issue so far on my end. A couple of clarifying questions:

• Could you confirm if disabling hardware acceleration and restarting Sublime Merge resolves the issue
• Could you confirm which model Mac you have

Kind regards, - Dylan

Disabling HW accel seems to fix this, so maybe will use that MBP pro late 2012
