I am 99% certain this is caused by disabling Hardware Acceleration on Firefox.
To recreate: 1/ On Firefox, Under Settings/Performance, un-tick "Use recommended performance settings" and un-tick "Use hardware acceleration when available". 2/ Restart Firefox 3/ Browse the web, watch gnome-shell MEM% rise in htop. Even if tabs are closed, memory isn't freed. 4/ Close Firefox - gnome-shell MEM% returns to normal. Firefox version is 137.0.2. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/2107504 Title: gnome-shell memory leak, oom-killed Status in gnome-shell package in Ubuntu: New Bug description: gnome-shell slowly increases in memory usage over several hours, and is oom killed by the kernel. This has happened at least 3 times in the last two days since 15 Apr 2025. I removed all extensions and restarted, but I can still see memory use increasing. jm@laptop:~$ lsb_release -rd Description: Ubuntu 22.04.5 LTS Release: 22.04 jm@laptop:~$ apt-cache policy gnome-shell gnome-shell: Installed: 42.9-0ubuntu2.2 Candidate: 42.9-0ubuntu2.2 Version table: *** 42.9-0ubuntu2.2 500 500 http://nz.archive.ubuntu.com/ubuntu jammy-updates/main amd64 Packages 500 http://security.ubuntu.com/ubuntu jammy-security/main amd64 Packages 100 /var/lib/dpkg/status 42.0-2ubuntu1 500 500 http://nz.archive.ubuntu.com/ubuntu jammy/main amd64 Packages jm@laptop:~$ gnome-extensions list --enabled jm@laptop:~$ [Wed Apr 16 14:57:28 2025] <TASK> [Wed Apr 16 14:57:28 2025] dump_stack_lvl+0x76/0xa0 [Wed Apr 16 14:57:28 2025] dump_stack+0x10/0x20 [Wed Apr 16 14:57:28 2025] dump_header+0x47/0x1f0 [Wed Apr 16 14:57:28 2025] oom_kill_process+0x118/0x280 [Wed Apr 16 14:57:28 2025] ? oom_evaluate_task+0x143/0x1e0 [Wed Apr 16 14:57:28 2025] out_of_memory+0x103/0x340 [Wed Apr 16 14:57:28 2025] __alloc_pages_may_oom+0x112/0x1e0 [Wed Apr 16 14:57:28 2025] __alloc_pages_slowpath.constprop.0+0x41f/0x9e0 [Wed Apr 16 14:57:28 2025] __alloc_pages+0x31d/0x350 [Wed Apr 16 14:57:28 2025] alloc_pages_mpol+0x91/0x210 [Wed Apr 16 14:57:28 2025] ? filemap_get_entry+0xf0/0x180 [Wed Apr 16 14:57:28 2025] folio_alloc+0x64/0x120 [Wed Apr 16 14:57:28 2025] filemap_alloc_folio+0x31/0x40 [Wed Apr 16 14:57:28 2025] __filemap_get_folio+0x14b/0x2f0 [Wed Apr 16 14:57:28 2025] filemap_fault+0x48c/0x8d0 [Wed Apr 16 14:57:28 2025] __do_fault+0x3a/0x190 [Wed Apr 16 14:57:28 2025] do_read_fault+0x133/0x200 [Wed Apr 16 14:57:28 2025] do_fault+0xf0/0x260 [Wed Apr 16 14:57:28 2025] handle_pte_fault+0x114/0x1d0 [Wed Apr 16 14:57:28 2025] __handle_mm_fault+0x64f/0x790 [Wed Apr 16 14:57:28 2025] handle_mm_fault+0x18d/0x380 [Wed Apr 16 14:57:28 2025] do_user_addr_fault+0x169/0x680 [Wed Apr 16 14:57:28 2025] exc_page_fault+0x83/0x1b0 [Wed Apr 16 14:57:28 2025] asm_exc_page_fault+0x27/0x30 [Wed Apr 16 14:57:28 2025] RIP: 0033:0x75e89119d424 [Wed Apr 16 14:57:28 2025] Code: 00 0f 1f 44 00 00 f3 0f 1e fa c5 f9 6e c6 89 f8 25 ff 0f 00 00 c4 e2 7d 78 c0 c4 41 31 ef c9 3d e0 0f 00 00 0f 87 ac 01 00 00 <c5> 7e 6f 07 c4 c1 7d 74 c8 c4 c1 35 74 d0 c5 ed eb c9 c5 fd d7 c1 [Wed Apr 16 14:57:28 2025] RSP: 002b:000075e8899fe498 EFLAGS: 00010287 [Wed Apr 16 14:57:28 2025] RAX: 0000000000000d91 RBX: 000075e88fe36d90 RCX: 0000000000000001 [Wed Apr 16 14:57:28 2025] RDX: 0000000000000000 RSI: 0000000000000025 RDI: 000075e88fe36d91 [Wed Apr 16 14:57:28 2025] RBP: 000075e8899fea20 R08: 0000000000000002 R09: 000075e8899fe9c7 [Wed Apr 16 14:57:28 2025] R10: 0000000000000000 R11: 0000000000000003 R12: 0000000000000010 [Wed Apr 16 14:57:28 2025] R13: 000075e891217300 R14: 0000000000000002 R15: 000075e88fe36d91 [Wed Apr 16 14:57:28 2025] </TASK> [Wed Apr 16 14:57:28 2025] Mem-Info: [Wed Apr 16 14:57:28 2025] active_anon:1727135 inactive_anon:5709216 isolated_anon:0 active_file:133 inactive_file:842 isolated_file:0 unevictable:338498 dirty:0 writeback:0 slab_reclaimable:75961 slab_unreclaimable:112307 mapped:4798007 shmem:5156980 pagetables:53092 sec_pagetables:0 bounce:0 kernel_misc_reclaimable:0 free:50979 free_pcp:662 free_cma:0 .. .. ..
