"Loading" indicator uses enormous amounts of CPU #243

Closed RalfJung closed 6 years ago

RalfJung commented 6 years ago

I've been working with a pretty slow internet connection for the last 30min, which means that some pages take many minutes to load. I noticed that my system got less responsive, and indeed, Firefox was using >100% CPU (where 100% is one core) when there are three "loading" animations going in Tab Center Redux.

I then closed the sidebar, and the CPU load immediately went down to <20%.

Looks like Tab Center Redux needs a full CPU core just to display three little animations?

This is on a 4k screen on Linux, using Gnome.

I tested this on my computer and couldn't see the spike, could you paste what about:support gives you?

Sure. I removed some of the modified properties as they contain private information.

Just saw this blip on my radar, we should do the same and it's literally a 2 lines fix.

Keith94 commented 5 years ago

This still seems to be an issue for me on the latest version.

RalfJung commented 5 years ago

@eoger Why was this closed? The problem is still present in the latest version (see https://github.com/eoger/tabcenter-redux/issues/385).

dos1 commented 5 years ago

This was closed because it was fixed. It just got broken again.
