Video card is Ati Radeon A3470, and color depth is 24bit. I've stored glxinfo output
if you happen to find any use to it.
I've also made (as soon as can't do anything more apart from this) some ST2 traces on an empty profile, empty window:StraceStrace (counters)
Ltrace was too large to put anywhere, even after a few seconds (several MB of log per second)Ltrace (counters)
On the second thought, the issue I have may probably exist because of some hardware problem (e.g. heating) -- in the morning, as soon as I turned on the computer, there was almost none CPU clogging, but it came back is a few minutes.
