These three checks are flaky failing. Wayland bots (GTK and WPE) from time to time happens to pass all three. GTK Xvfb is consistently failing.

First failure: r267136-r267140 (Includes GStreamer 1.18 update and mesa patch in the SDK)

Similar failure in the following test since the same range:

The results dashboard suggests this was fixed by r273309. I'll unflag these two.
