Actually, I was wrong, now the memory usage for GMail tab grew to 3 GB with 20220329.git681281e4-0ubuntu3.6 as well, so it must be unrelated to linux-firmware after all.
Sorry for the noise. You can close this bug and I'll have to go find where the problem really came from. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-firmware in Ubuntu. https://bugs.launchpad.net/bugs/1998390 Title: 20220329.git681281e4-0ubuntu3.7 causes excessive memory usage in GPU- using applications Status in linux-firmware package in Ubuntu: New 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.
