[Bug 578395] Re: jpg corruption of large images

[phoenixbbs]

...an interesting variation I noticed on the above happened when I went
to take some screenshots of the variation in the black band - as I hit
"PrtSc" the image becomes more corrupted than it already was, and was
able to repeat this behaviour as often as I wanted.

Whether this could be an error with the gfx driver or memory allocation
on the system, I don't know, but it seems to me as though either the
screen memory is being overwritten by system data, or a memory pointer
is altered for some reason (the system does lock randomly at times,
complete hard lockup forcing a hard reset - but works perfectly under
'doze)
