Description Michael Catanzaro 2022-10-13 07:02:52 PDT 
Make sure Ephy Tech Preview is closed and is your default browser. Also make sure it is GTK 4 (we have switched it from GTK 3 to GTK 4 again for testing purposes). Click on a link in any application (mail client, feed reader, whatever). For me, Epiphany will crash on startup. Unfortunately, Exalm cannot reproduce this bug, so maybe it's only me. Looks to be related to accelerated compositing mode.

The backtrace:

The problem is here:

    auto* pageSnapshot = gtk_snapshot_new();
    if (!webViewBase->priv->isBlank) {
        ASSERT(drawingArea->isInAcceleratedCompositingMode());
        webViewBase->priv->acceleratedBackingStore->snapshot(pageSnapshot); <-- this is line 742 for 2.38.0
    }

Shame that's not a release assert.
