Description of the issue:
Brave became so unusable I have to type it from Safari. Rendering of every page takes so long, that I opened debugger and it shows it takes 3 second for single frame to render!
OSX menu bar works fast and very responsive, menu under right side burger is sluggish as hell too
How can this issue be reproduced?
- Open brave on Macos
- Grab coffee
- Go to any page or open a new tab
- Refill coffee
Sub 100ms new tab
Brave Version( check
Version 0.69.135 Chromium: 77.0.3865.120 (Official Build) (64-bit)
macOS Mojave 10.14.6 (18G103)
All extensions are disabled. Same problem.
Moving Brave-Browser folder (aka fresh profile) did not help
Reinstall did not help.
Fresh install did not help.
Beta version did not help - same problem.
Question: internal adblock – could it be possible that you have “runaway regex” problem (but there is no mem explosion, so probably no), or checking every pixel for every tick of some timer for spam? (but there is no CPU grind…)
This image shows the new tab frame stats in debugger.
Please let me know if you need any additional info, or plug some debugger into running app
