Bug 247954 – [GTK4] Crash loading webkit://gpu

• Status: RESOLVED
• Resolution: DUPLICATE
• Component: WebKitGTK

[Michael Catanzaro]

With GTK 4, loading webkit://gpu in Epiphany Tech Preview causes the UI process to crash.

My debuginfo is broken currently, so I'll need to get a backtrace later. Creating this now just so I don't forget....

[Michael Catanzaro]

Got a backtrace. The crash is deep in GTK's GSK. There are no Epiphany or WebKit frames anywhere in the backtrace:

Accordingly, I will report a new bug to GTK. But I'll leave this open here as well, due to major impact.

It's exactly the same as bug #233592.
