Delay in applying selected tab highlight for large number of tabs #376

Open Livven opened 6 years ago

Livven commented 6 years ago

Since the last version (0.7.0) there is a noticeable delay before the selected tab is highlighted (and the previous tab loses its highlight) when switching tabs with a mouse click. No delay when switching tabs with Ctrl+Tab, or on 0.6.3 or any previous version.

Note that this only affects the tab sidebar itself. The original tab bar and the actual tab switch still happen without delay.

Also only seems to happen with a large number of tabs. I have windows with >1000 where it happens, but <10 are fine.

Just noticed the delay happens for any change in the tab sidebar, i.e. also creating and closing tabs.

I noticed it before, too. We should narrow it down to a specific commit, if possible.
