Title:
20220329.git681281e4-0ubuntu3.7 causes excessive memory usage in GPU-
using applications
Status in linux-firmware package in Ubuntu:
Invalid
Bug description:
Upgrading from 20220329.git681281e4-0ubuntu3.6 to
20220329.git681281e4-0ubuntu3.7 caused the memory usage for a GMail
tab in Firefox to go from 300-400 MB to 3 GB. I saw a similar large
increase in memory usage in Chromium.
I suspect some bug is being triggered in the Intel driver/Mesa stack?
Reverting to 20220329.git681281e4-0ubuntu3.6 fixes the problem. I
tested back and forth multiple times to confirm that it really was the
linux-firmware upgrade that caused the issue.
This is on a Thinkpad X1 Carbon 6th gen with an Intel HD Graphics 620
GPU running up-to-date jammy.
