I tried searching these forums, but for this problem it's hard to know effective search terms.
In the latest version of Chrome, but also in Opera, I often get black rectangles, at other times rectangles repeating part of the web page from higher up. See attached two images. If I change to a different tab and back again it normally, but not always corrects itself. Sometimes it can take a few goes. Also, hovering over the rectangles with the mouse pointer often makes the rectangles disappear, but not always.
It only started happening a month or two ago. I don't think I've installed any new software or anything, which could have made this happen. I have turned off hardware acceleration in both browsers, as is recommended by some to help solve similar problems. But to no avail.
Any suggestions would be appreciated, as it is getting a bit distracting. Happens many times when browsing.
On the first image, please ignore the fact that it shows a search for a word... this is not related to the problem. I just happened to be doing a search when I took the screen dump. The second image shows black rectangles (on a forum I didn't end up posting on). The problem used to be just black rectangles, but this week it started showing rectangles with the repeated parts of the page (shown on first image.)
I use Windows Vista Home Premium, SP2 ... which I've always found very good.
