Thanks for a bug report. It's due to webkit2gtk3 changes. It's tracked upstream as [1]. I can backport the change, as there's not planned any upstream release with the 3.42.x and older versions.

Michael, I see you made a 2.36.0 webkit2gtk3 update for f34, f35, f36 and rawhide. The related change there breaks Evolution. While it's a good change in general, it breaks user experience in stable Fedora, which can be understood as a regression by the users. There is surely not being done any upstream Evolution release for the 3.40.x, similarly as none for the 3.42.x. It's really unfortunate to break apps this way.

Hi Milan,

Sorry for the breakage. :/ The F35 update has already gone out. Do you want me to hold the F34 update to give you more time to react?

FEDORA-2022-b375b6a0f7 has been submitted as an update to Fedora 35. https://bodhi.fedoraproject.org/updates/FEDORA-2022-b375b6a0f7

That's okay, I just filled evo updates. They can work with older webkit2gtk3 too, thus they can get to the users also before the webkti2gtk3 update (they should go ideally together, but as the f35 is out already, it doesn't matter that much).

I've installed with bodhi and tested it. Working fine, bug is fixed.
Thank you guys the quick fix!

David

I've unset autopush on the F34 update, to ensure your update here hits stable first. Most likely, I'll wait for 2.36.1 before pushing the update to F34, because some other regressions were noticed too.

Anything I should know about, make a fix on the Evolution side for?

Note the only downside here is that I fix evo, but other apps, which may or may not be affected, still are or are not affected. Of course, evo's way of using the WebKitGTK is very specific and complex. This particular theme thing was related to iframe-s and color propagation inside the iframe.

Ah, no, not anything that would require changes in applications.

Right, but this sort of change is considered normal because web APIs are not stable. I doubt that apps other than Evolution would have been affected, though of course it's impossible to say for sure....

Good. Maybe you'd be interested in this thread, which opened yesterday on the evolution-list:

Looks like a crash that needs to be reported on WebKit Bugzilla.

Okay, thanks, I'll ask the user there to report it or to provide more details.

By the way, the message mentions a missing dependency on swrast-dri.so, which can be a packaging issue, maybe.
