Lots of users reporting this issue (Spotify) in this thread: https://community.brave.com/t/spotify-keeps-crashing-in-brave/532078/23

I can confirm Spotify is leaking memory and crashes after some time on latest v1.64.109

Latest Chrome 123.0.6312.58 doesn't have this issue. It's a shame that I have to use Chrome to play Spotify.

Looks like its in Chromium issue

I noticed that high memory usage is not reported by task manager. For example hover over tab will show 3.7GB memory usage, while task manager shows 250MB.

an upstream bug: https://issues.chromium.org/issues/329580320

The upstream bug is fixed and Chromium claims it helps to resolve most of the issues for them. However, it cant still reproduce the issue on a recent nightly (cr126) with chromium fix.

I've managed to grab and symbolize a memory-infra heap dump, but the data is controversial (Release optimizations?):

I've managed to get the correct stack. It matches the crash dumps and the details in the chromium issue.

I've pushed CL to upstream that should improve the situation: https://chromium-review.googlesource.com/c/chromium/src/+/5670619/1

However, despite Chrome also has this issue, it is more severe in Brave Browser. The reason is an avalanche of requestIdleCallback originated from ReChapta javascript (from spotify.com) Each round (typically 100ms) the page got N callback fires and schedules N+1 new requestIdleCallback with timeout (usually 3000ms).I haven't managed to catch the same for Chrome.
