It appears I was confused and most recent testing _did_ happen in the
same session post-reboot, see timestamps in log snippet below;
The bug recurs after the display goes to DPMS standby/sleep. It also
appears the "display corruption on switching modes" occurs after the
display has its first (or multiple) chances to sleep as I hit it now
flipping to 1280x720 the second time in the session - no more clear
1280x720, again a wait for a garbled screen to revert.
While Xorg log shows the machine rereading DDC/EDID data when things are
woken out of DPMS (and the seizure-inducing flicker recommences), xrandr
shows _no_ difference in modelines before/after... not really a surprise
but was worth confirming.
[I should probably be hunting this bug upstream where it's probably
already fixed; maybe another night.]

Title:
R300 (RS480): Intermittent flickering corruption top half of display
(VGA, 1080p)
Status in “xserver-xorg-video-ati” package in Ubuntu:
New
Bug description:
Any suggestions where to start welcome:
Compaq SR1611NX desktop, "Radeon Xpress 200" RS480 (R300) graphics.
HP LV2311 LCD connected via VGA because that's the only output on this
hardware.
The VGA output used to be a little "less than perfectly stable" with
older X.org (versions shipped from Ubuntu 9.x to 10.x). Unknown
improvements since then have made the overall display much more stable
- no more shifty horizontal flicker.
In tradeoff, now the top half of the display occasionally flashes
distractingly for fractions of a second (single frames?) with "memory
cruft" as you might expect to see during boot or graphics init -
generally offset large "checkerboard"-esque blocks of black and color
with no obvious relation to what's on the display. This would seem to
suggest it's an actual GPU/driver issue rather than a glitch on the
VGA/monitor end of things.
No idea how to trigger or reproduce other than that it will generally
occur at least once within each 15 minutes or so of use. Expanding
and retracting the dash (very slowly due to the current regression -
takes about 5+ seconds to fade in and dismiss) will sometimes set it
off, however.
Recommendation for screen-recording software to see if it turns up "in
software" short of pointing an actual camera at the screen?
