Unusual CPU usage spikes with 32-bit version

[narinishi]

Am using 119.0.6045.192. Switching from 64-bit to the current 32-bit zip. Have been noticing brief spikes in CPU utilization which render the browser temporarily unresponsive.

I assume that these spikes are not generating dumps.

I wonder if you can open Process Hacker or similar tool, open the process producing the CPU spikes, then open the specific thread causing the spikes, and show me the call stack for that thread?

[narinishi]

No dumps. It's only unresponsive for a few seconds which isn't enough time for me to find the relevant thread.

Just happens intermittently, can't figure out a specific way to reproduce.

I managed to catch this.

Also, after my computer has been in standby, when I switch to Supermium, it takes a while before it's responsive, whereas I also have Chromium 109 browser running which responds right away. Here I have captured an image of one of the threads

Seems to not occur if running with --no-sandbox - for reference, it can be confirmed this flag is active by checking chrome://sandbox/

do you use the same extensions or have the same number of tabs open at a time in both browsers ?

Similar extensions, and other browser was more immediately responsive with tabs already open vs Supermium with no tabs open.

I don't know the actual cause of my issue #158 but it seems to have gone away since then...
