Some flatpak apps shows only blank screens on Fedora 35

Ever since I installed F35, some flatpak apps such as Bitwarden and Spotify only shows blank screens (using nouveau driver here). I have already filed bug reports here and here, but I was wondering if someone else is also experiencing this or, even better, has a workaround to suggest…

It is worth noticing that other flatpak apps such as Telegram and Slack are working just fine (even though I suspect Slack causes some occasional gnome-shell segfaults, but that’s a whole different issue AFAICS)
