hi, thanks for caring, re 1. yeah, that's right, I got only the 3 default extensions installed re 2. and 3. I think I cannot do this anymore, cuz the problem suddenly disappeared when I reset the "Tweaks" setting to default. So, I reckon, it got something to do with "unlucky" and/or compromised Tweak settings, but I can't tell with ones. I set them back to the setting I *think* I've had before. but the gnome-shell process(es) stay(s) relatively cool, now.
and yes, I got animated indicators in my panel like indicator-multiload and clock seconds, however this was only a small percentage in difference. The seconds make up almost no difference at all, and when starting indicator-multiload, now, the gnome-shell only reaches like 25% CPU usage instead of 60-100% without indicator-multiload (prior to resetting the Tweak settings to default). And I don't think it has to do with my Firefox browser or Thunderbird mail client, cause also now when open all of them even with multi Firefox instances (profiles) and Discord, MS Teams. Telegram, Nextcloud client any many more the gnome-shell still stays absolutely cool: top - 10:13:50 up 1:02, 1 user, load average: 2,16, 2,17, 1,59 Tasks: 377 total, 4 running, 373 sleeping, 0 stopped, 0 zombie %Cpu(s): 31,3 us, 1,8 sy, 0,0 ni, 65,3 id, 0,1 wa, 0,0 hi, 1,5 si, 0,0 st MiB Mem : 7960,7 total, 402,0 free, 5835,6 used, 1723,0 buff/cache MiB Swap: 26058,0 total, 25075,5 free, 982,5 used. 1147,8 avail Mem PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 12683 tobias 20 0 2653208 300408 224756 R 108,6 3,7 12:59.40 Web Content 8685 tobias 20 0 3916848 629076 301284 S 38,1 7,7 6:35.34 firefox 2982 root 20 0 604680 339056 319360 R 27,2 4,2 8:05.53 Xorg 3216 tobias 20 0 5564976 892044 80780 S 9,9 10,9 7:16.01 gnome-shell 9149 tobias 20 0 4257832 518540 123472 S 3,3 6,4 2:01.05 thunderbird 10894 tobias 20 0 4063956 48868 19612 S 2,3 0,6 0:05.50 teams 2983 root -51 0 0 0 0 S 2,0 0,0 0:55.11 irq/35-nvidia 808 root 20 0 0 0 0 S 1,7 0,0 0:53.74 nvidia-modeset/ 10486 tobias 20 0 21,0g 159864 46864 S 1,7 2,0 0:43.80 Discord 12272 tobias 20 0 818300 51952 35748 S 1,7 0,6 0:11.74 gnome-terminal- 10210 tobias 20 0 4928588 62172 20264 S 1,3 0,8 0:24.89 Discord 386 root 19 -1 127172 63600 62776 S 0,7 0,8 0:06.07 systemd-journal 10826 tobias 20 0 2508384 352328 49164 S 0,7 4,3 1:15.08 teams 13432 root 20 0 0 0 0 I 0,7 0,0 0:01.30 kworker/4:0-events 1520 root 20 0 2548 720 668 S 0,3 0,0 0:17.57 acpid 2985 root 20 0 0 0 0 S 0,3 0,0 0:06.63 nv_queue 3149 tobias 9 -11 4366744 11612 8696 S 0,3 0,1 0:14.64 pulseaudio 8646 tobias 20 0 4177312 564096 253408 S 0,3 6,9 3:23.27 firefox 8858 tobias 20 0 20,6g 285284 186692 S 0,3 3,5 1:02.59 Web Content 9072 tobias 20 0 14,6g 259344 46428 S 0,3 3,2 0:32.74 WebExtensions 9287 tobias 20 0 3558884 212352 42240 S 0,3 2,6 0:28.64 teams 12395 root 20 0 0 0 0 R 0,3 0,0 0:02.24 kworker/3:1-events 13057 root 20 0 0 0 0 I 0,3 0,0 0:01.06 kworker/2:1-events 13070 root 20 0 0 0 0 I 0,3 0,0 0:00.97 kworker/1:4-events 13293 root 20 0 0 0 0 I 0,3 0,0 0:01.57 kworker/5:2-events 13561 root 20 0 0 0 0 I 0,3 0,0 0:00.99 kworker/0:1-events 13814 tobias 20 0 12488 3968 3092 R 0,3 0,0 0:00.08 top 1 root 20 0 172532 12276 5060 S 0,0 0,2 0:06.69 systemd -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1928791 Title: gnome-shell runs on 60--100% CPU usage To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1928791/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
