You mentioned before: I just tested how Chromium video playback behaves after waking from suspend and it has a similar problem. The difference is that with Chromium only rendering of the page is broken and refreshing it fixes the problem. With Firefox the whole browser window disappears and there's no way to restore it. Now I got confused. Once you say only FF and once you say Chromium also has the problem And all of this happens "after suspend". I wonder what has TDE to do with all of this at all. As mentioned before shooting in all directions does not make you win a war. I think you are younger and I allow myself giving you an advise or two. 1. Respect your time and the time of others. 2. Adapt hardware and software to your needs. So let me explain a bit. You insist using NVidea card with proprietary driver and complain on the TDE user list that it has some kind of issue. I just don't understand why you are doing all of this. I found out it is better to use Intel (the embedded card) as it has good to perfect support not only from Linux but also from Intel. To my understanding and experience older hardware has in general much better support, so using 4-5y old hardware saves money and has stable drivers. TDE runs perfectly well on each of the machines complying to that rule including FF. 1/2y ago I had similar problem on the RPi4 I bought just to play with, but it was solved in the driver and FF is working perfectly well there too. I don't know if it helps. And anyway I have a feeling that the answer to your original question is NO and it seems no one tried it.
