Nice site, indeed flawless in chromium here
Also tried the other sats and animation.

Yes that ctrl alt F1 .. FX
 before I posted that ssh reply I tested ctrl alt F1 on my Pi4 and
nothing happened, .. so thought it was blocked too.

But I see now it is because I am running the X server in terminal 1 ;-)
ctlr alt F2 works,
Not a standard system, changed it to fvwm and xfm, 9 virtual desktops.


Normally ctrl alt F7 should get you back in X (if server is still up).

After that site and chromium closed I see 1.2 MB swap used,
did not check before I started chromium, has been on some time now
uptime
 21:10:08 up 12 days,  8:13, 16 users,  load average: 0.42, 0.53, 0.69
tripped over the Pi USB power cable 12 days ago, had to reboot...
is on UPS.
swap stays good in control after changing 'swappiness' etc.
