Hello,

As you can see in the video attached, if I open a new tab (Speed Dial) while I'm on a webpage playing something, the animation when I close the tab closes is very laggy, and sometimes (but I couldn't get on camera this time) even the opening animation lags a lot.

Here is a recording of the issue, look closely when I open the tab, and then close it, you'll notice lag.

How can I fix this lag?
