Brave browser lockups

[Raycoms]

Description

Fairly regularly when loading and rendering a page, brave locks my entire computer.

Steps to Reproduce

1. Surf normally
2. Switch between tabs and load new tabs
3. "lag" on the entire computer level

Actual result:

I've noticed that at these moments of lag in htop the CPU usage spikes heavily.

Expected result:

Of course I'd expect it to not lag at all.

Reproduces how often:

Looks like your cpu is getting hot. You should first analyze the rest of the processes. Don't think it's an issue caused by brave..

[Raycoms]

All other things run fine though, and it doesn't happen with chrome.

This is from htop.

This is still happening with Brave, and I had to switch temporarily to chrome now because it doesn't temporarily lock up my computer while browsing.

At: brave-beta 1.2.36-1

[bsclifton]

There is a known GPU issue we have which we're fixing- I'd like to ask if folks can try changing a config value

@Raycoms can you please try visiting brave://flags/#enable-oop-rasterization and then DISABLING this flag? May require a restart of Brave after changing. But worth a shot. Please let us know!

[Raycoms]

I feel like it is happening a little bit less again now, but it is still happening.

[Raycoms]

Correction, it doesn't happen less. Just seemed like this for a few minutes.

Some extra info:

• This happens:
  a) When I load a new side this sometimes gets stuck and then hangs my entire computer
  b) When I switch between tabs when nothing is loading.

[Martina-Neumayer]

@Raycoms Thnx for the output. Yeap.. As I thought, it is an Optimus based machine (Nvidia+Intel gpu), where this issue most often occurs.

Btw.. Update your kernel.. 4.19 is a bit old one as for the Arch based system ;)
And you can also look here.. There's a thread with similar problem. #6098

[Martina-Neumayer]

For me disabling the OOP rasterization changes nothing. Hangs are still there.

[Raycoms]

Oh nice, didn't know there was another open issue yet. Similarly to how you described it, it started after an Nvidia driver update for me. But it doesn't happen with any other browser at all (At least not with chrome or firefox) so it must be something brave specific.

[Martina-Neumayer]

@Raycoms Yes.. Seems that it happened every time the nvidia driver update is released. I think the entire Chromium base is affected as well from this issue.

[bsclifton]

Closing this issue as stale - for folks experiencing this, I'd recommend checking out one of these two issues:

• Brave freezes or hangs on launch Brave freezes or hangs on launch when there are a large number of Cookies and other site data #9481
• Horrible lag with chromium-based browsers on Linux Horrible lag with chromium-based browsers on Linux  #8436
