My hardware is a Pi 3B+ with official 7" DSI touchscreen and HiFi berry AMP2.
In addition to the sudden memory usage increase of chromium after some time I noticed the CPU usage to be significantly higher all the time compared to 6.7.1.
I'm seeing ~18% on 6.7.1 vs ~ 79% on 7.1.0 (just after booting and stays at this level for minutes).
Moreover I installed different browsers and updated chromium on 7.1.0 - didn't make a difference, at least considering the high CPU usage. With different browsers (Firefox, Vivaldi, Midori) the UI is very unresponsive right from the beginning and CPU load is even higher (ranging from 90% to well above 130%), so I didn't check about memory usage spiking.
As last test I updated the whole Raspi OS via apt update && apt upgrade to 10.9 - also didn't make a difference.
So has anybody else made progress investigating this?
For now I restored my backup of 6.7.1.
Tim's already answered so I won't recite what I did to try (and fail) to repro the "significantly higher all the time" report using a fresh install of 7.1.0 on an RPi3B+ with the official DSI 7-in touch display. I'll leave it running all day to see if I can repro time-dependent behavior.
A problem with "me too" posts is that they almost always fail to include sufficient information to determine if they are manifesting the same issue or a different one. This thread is specifically addressing the issue of moOde becoming completely unresponsive because a chromium-renderer thread is hogging system memory. That is more than just seeing higher memory usage (how did you determine this, by the way?).
If you want to pursue the matter, then immediately after reboot run "moodeutl -l" from the command line. Post the output in a code box. As soon as you see the significantly higher memory usage run "top -b -n1 -1" from the command line and post the output in another code box. That gives us some meat to chew on.
Report also what operating conditions are necessary to repro, e.g., idle state or playing state or paused while playing state, etc.
