But I've also proposed a fix for Mesa:
https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/25173
You only need one fix.

The output from `top` was always well behaved while chromium was open,
until it was closed, at which point xorg cpu's usage went through the

Still, making Xorg think there's a massive pixmap leak is causing it to
become unresponsive while it frees them all when Chromium exits.

I captured the 'top' and `xrestop` as attachment.
The `xrestop` show quite a lot memory usage, but it is not aligned w/ `top`.
`top` shows no obvious memory leak.

I try the self build Chromium 118.0.5966.0, and run below command for h264 hw
decoding.
After 30min playback, the chromium is well.
