[10.5x] Redraw flicker (with video)

[10.5x] Redraw flicker (with video)

Hi,
I have an issue in mentioned versions, maybe you know a solution
I searched for "flicker", "redraw", "refresh", found nothing relevant

WHEN:
opening site-wide links, loading page of a certain site
various websites, not many, but still present

WHAT:
despite being single site and pretty much everything is in cache, the page's images flickers on redraw
the way that whole site loads pretty much instantly (seamlessly) but without images and they suddenly appear a moment after,
thus causing flickering when moving through site

reinstall didn't help

moving through most other websites feels seamless

images are neither big nor numerous

WHAT I TRIED:
Changing Loading -> Redraw instantly/after X secs/when loaded -> ok until new Opera start
Clearing Cache -> ok until new Opera start
Show Cached images only -> mostly ok until new Opera start

ok = seamless load with no flicker, as it should be
sites are hosted nearby and latency is very good so that's not the issue

SITES:
there were several, one I can think of is http://www.meliorannis.com ...it's not english but I think it doesn't matter, there's menu on the left site
it also happens on a site I created, however I wouldn't like to make it public yet but I'd provide any info needed
I'll edit when I find more

VIDEO attached [wmv 1.5MB]
(I believe some of the flickers were lost in the video due to compression algorithms, but there's enough of them)
this flickers to white, my site to black so it's most likely background-color

There's probably some bugtracker? But I post here first as I'm not sure if it's not some widely known simply fixable issue

Current version: 10.53 (3374)
OS: Windows 7 x64

Thanks a lot for any hints, will provide more info if needed

EDIT:
Having some problems with attaching the file so here:
