There's "NativeLayerWaylandRender::CommitSurfaceToScreenLocked() - missing front buffer!" which may be related.

Attachment: Bug 1959609 [Wayland/HDR] Don't release layer back buffer on NativeLayerWayland::Unmap() r?emilio

Don't release native layer back buffer on unmap as the layer can be mapped again and compositor expect it still has the content painted before.
Use NativeLayerWayland::DiscardBackbuffers() only to release back buffer resources.
Add more logging to layer creation.
Convert assertions to MOZ_DIAGNOSTIC_ASSERT() as we want to run them in non-debug build too.
