--- Comment #3 from Alexey Dokuchaev <[email protected]> ---
(In reply to Graham Perrin from comment #1)
> Can you name one? And the exact version, please.
For example, the latest version of Stellarium, 23.1 stops working -- it hangs
on start while eating all available CPU cycles after VT switch (which is likely
the trigger, not going in and out of S3) as I've reported earlier:
https://github.com/Stellarium/stellarium/issues/3145.  Previous versions are
immune to this bug.

> What's the graphics hardware?
Looking at the issue linked in comment #2 it can happen on both AMD and Intel,
e.g. UHD Graphics 620 (Kaby Lake GT2) in my case.
