Created attachment 445302 [details] backtrace of eolie 105511 This is also tracked as issue https://gitlab.gnome.org/World/eolie/-/issues/389 The issue can be reproduced by starting a web application for twitter and playing an animated gif in this session. It was not tested if the system freeze also occurs when playing video. os= Ubuntu 21.04 CPU/GPU = AMD Ryzen 3700U
increased severity to blocker due to system freeze
The crash is bug #201507. We've struggled for years to find a reproducer for this. If you're able to trigger it reliably, then you're probably going to be a hero here. The system freeze is obviously not our fault though. That said, check to make sure WebKit is not using an excessive amount of RAM. If RAM usage looks good, then I wonder if you have uncovered a bug in mesa. If not, who knows where....
Sorry to say i've likely mixed up some things here swichting between too many topics too often. The Twitter Web App is one run in epiphany but the backtrace here is for an Eolie crash. I've just crashed eolie again and am attaching another backtrace.

It's exactly the same crash, and I was going to say "the problem is your EGL is somehow broken," but... last I checked, you were using X11 and therefore getting GLX rather than EGL, right? Could you please open up webkit://gpu, copy/paste the output into a file, and attach it here?
Created attachment 445313 [details] eolie crash on tab loading 23839 crash was triggered by enabled use of media, images and loading both the att.com and nu.nl URL the nu.nl URL redirects to https://myprivacy.dpgmedia.be/ or https://myprivacy.dpgmedia.nl/ depending on what content loads after which the crash is produced, now trying to reproduce
Also, please confirm what WebKitGTK version you have (easiest way is to check the About dialog in Epiphany).

Weird. That's definitely a WebKit bug, but it's not *this* bug. Could you report a separate bug for it please?

OK, I see you've indeed switched from X11 to Wayland. So this issue is different from https://gitlab.gnome.org/GNOME/epiphany/-/issues/1642#note_1317772.
I've been using wayland for every session and every coredump after you mentioned it was considered obsolted in terms of development efforts.

Created attachment 445331 [details] eolie backtrace 17461
(In reply to LJoris from comment #12) > the syslog output from eolie, paired with a backtrace should this help That's hard to read, but the backtrace is very useful. That is a *third* crash, the at-spi2-atk issue I mentioned earlier. To keep the bug reports readable, I really need to insist on a separate bug report for each crash. Currently we have: * This bug for the original Nicosia::GCGLLayer::makeContextCurrent issue * Unrelated WebKitWebsiteDataStore crash (comment #6), needs a separate WebKit bug report * Unrelated accessibility crash (comment #13), needs a separate WebKit bug report *and* and at-spi2-atk bug report. Definitely an at-spi2-atk bug here, *probably* also a WebKit bug. (Not sure.) * A fourth unrelated crash after receiving an X server error (https://gitlab.gnome.org/GNOME/epiphany/-/issues/1642#note_1317772, probably a mesa bug, no backtrace for this one yet) It's a lot of bugs. This might be a record: you must be very unlucky! Anyway, at least now with good backtraces you have enough to prove there are real bugs, so we are making some progress.
I'll see what i can do. Note the i'm also learning how to distinguish the different bugs. For now i only distinguish by looking at EXE. I'm not affected by these bugs, only whatever dares to work with Webkit is.
Since my last post i've had repeat system freezes whenever an animated gif plays in the epiphany browser. There is no coredump generated and i don't know how i could generate any thing useful when reproducing this event. Since it is reproducible by playing an animated GIF i'm willing to spend more time on this but i need to know what to do to collect meaningful data.
checksec --proc=epiphany * System-wide ASLR (kernel.randomize_va_space): Full (Setting: 2) Description - Make the addresses of mmap base, heap, stack and VDSO page randomized. This, among other things, implies that shared libraries will be loaded to random addresses. Also for PIE-linked binaries, the location of code start is randomized. See the kernel file 'Documentation/sysctl/kernel.txt' for more details. * Does the CPU support NX: Yes COMMAND PID RELRO STACK CANARY SECCOMP NX/PaX PIE FORTIFY epiphany 119202 Full RELRO Canary found No Seccomp NX enabled PIE enabled No
So your distro builds it with hardening flags. Great. Totally irrelevant to this issue.
The reason i shared the checksec output was to show what is the context for this and the other issue reported should that matter with interpreting backtrace information. In the meantime I've ran an exhaustive memory integrity check. No test failed, no warnings of any kind were reported.
At this point i notice 'some' improvement in that the system freeze is less accute. Web/Epiphany freezes but now the numlock remains responsive which was not the case before. I'm not certain what to attribute this improvement to. the animated gifs now appear to play well but when video plays (with sound?) the system still freezes
