I have a strange issue that happens with both the Chrome and Safari browsers. It only happens when the browser is maximized on my 2nd monitor.

A rather large (toolbar sized) rectangle obscures the top-left of my window. It occupies about half the screens width and is a few textlines high. It is filled with junk or old screen contents. It does not scroll.

Hard to describe but here is a screenshot (I've added the red box).

So, is this a known problem? Anything I can do about it?

  • Well, at least I guess it's safe to say that it's Webkit related. – Der Hochstapler Mar 17 '12 at 17:41
  • @OliverSalzburg - yes, that kind of reassured me. Makes malware less likely. – Henk Mar 17 '12 at 17:47
  • Operating system? – iglvzx Mar 18 '12 at 18:22
  • It's running on Win7 HP, SP1. Second monitor on HDMI, both are 1920x1080 – Henk Mar 18 '12 at 18:26
  • Do you have DWM disabled? – Tom Wijsman Mar 19 '12 at 14:56

You have to update video drivers since modern drivers do not allow to reduce hardware acceleration level on Win7 to eliminatie "artifacts"

  • But what makes you think that this is an acceleration artifact? – Henk Mar 18 '12 at 18:47
  • Because millions of others do not have it? – ZaB Mar 19 '12 at 0:12
