Reviewing state and this bug after wondering why the system wasn't flickering after a reboot, I am reminded that entering and leaving monitor sleep seems to be prerequisite to reproducing the issue.
So every boot is fine until the monitor goes to sleep, and disabling it would be a workaround. ** Description changed: + [Edit: Issue narrowed down to Something Bad Happening when the display + goes to sleep.

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? + Recommendation for screen-recording software to see if it turns up "in + software" short of pointing an actual camera at the screen?
