Version 0.68.140 - slow on Mac OS 10.14.6

after updating to Version 0.68.140 suddenly working in brave became “slow” during regular usage / tasks: in many occasions, typing stopped and the “mac wheel” is spinning - then, if you continued typing, the text appears with some delay. Same happens when opening new tabs fast and clicking on links etc. - delay is up to seconds (up to 4 Seconds). Even clicking from this text box into the headline box just took 2 seconds.

The strange aspect is, that this happens many times but not all the time.

CPU Usage goes up to 102% (on a 2.7 GHz Intel Core i7 with 16 GB Ram) running nothing but Brave.


My macbook pro, has brave around the 2-4% cpu usage (only 2 extensions Ubo and useragent switcher), tho I would look at clearing out the cache (then restarting) and disabling any/all extensions. as a start.

i have completely uninstalled / deleted and reinstalled brave

Is it performing better?

i only wrote the ticket after I encountered the same problem after the hassle of uninstall and installing it again.

If it helps any, I am seeing something similar. I have not been on line much over the last couple of weeks, but in that time my Brave experience has changed significantly. Here are my particulars:

OS: Mac OS Mojave 10.14.6. Brave: Version 0.68.142 Chromium: 77.0.3865.90 (Official Build) (64-bit). There is a notable lag on browser startup (“notable” meaning 0.9-1.1s). There is a notable lag when clicking “=” for a new window. There is a notable lag after the blank window comes up, during which “chrome://newtab” shows in nav bar, before the Nav changes to “New Window”, then a bit later the stock “Ads and Trackers Blocked” summary window comes up. Then typing a straightforward URL, like, has a similar lag before it renders.

Overall is it takes 8-9 seconds from a new tab to the window rendering. Similar, if maybe a bit let lag seen when clicking on the x to close the tab.

CPU runs around 8-9% during all this.

Opening the “About Brave” window showed all of these things (6-7s to rendering), plus, mousing over the version info was jerky and blotchy, not smooth. The visual feedback was running behind the actual mouse position.

Chrome works fine. No other apps seems affected. Private windows are also slow. Tor windows are incredibly slow.
