Is the problem fixed if you disable async image decoding for animated images? You can disable it in mini browser from Settings/Enable Animated Image Async Decoding.

If the problem is fixed when async image decoding is disabled, you can disable async image decoding by making ImageSource::canUseAsyncDecoding() returns false for GTK always. This will restore the old behavior till you have a proper fix.
