I'm now finding that the webview is blank in all the apps that use it (epiphany, Yelp). The web inspector shows up fine, and when I move the cursor around the screen it changes as if it were hovering over the actual web content. Running either yelp or epiphany with WEBKIT_DISABLE_COMPOSITING_MODE=1 makes the webviews work correctly again, so I suspect this is an issue with the accelerated hardware compositing. Not sure what libraries are involved with that, so I don't know which versions to give you. I'm happy to provide whatever you need to track down the bug!

Try loading webkit://gpu and paste the output here. The flaw in this plan is that it probably won't load unless you use WEBKIT_DISABLE_COMPOSITING_MODE=1, which will impact the results it shows, but we'll just have to keep that in mind.

Those issues don't look super similar to me, especially since the assembly snippet I've posted seems to be throwing out the result of createOffscreenContext, dereferencing some random variable, and calling it as a function. However, I might be missing something and I'm sure you know better. Do you think those two bugs are related to the blank webviews? I don't see segfaults then Additional context: The flatpak'd wip/exalm/gtk4 branch of epiphany (using the same version of webkitgtk) works perfectly fine on the same system Reply at: https://bugs.launchpad.net/ubuntu/+source/evolution/+bug/1966418/comments/9 ------------------------------------------------------------------------ On 2022-03-23T21:35:24+00:00 Michael Catanzaro wrote: (In reply to Michael Catanzaro from comment #8) > I suppose you're hitting bug #201507 and/or bug #233578.

It's caused multiple crashes in the past, if you're brave enough to wade through the history of those bugs....
