Windows 7: Win 7 - Top 1" of full screen window becomes white/click-through

26 Nov 2014   #1

Windows 8.1 64 bit
Win 7 - Top 1" of full screen window becomes white/click-through

I've been seeing what appears to be a windows bug, but I havent been able to locate any discussion or permanent fix. In a application that has been maximized, the top inch (edge-to-edge across the top 80-100 pixels? or so, enough that the office ribbon is mostly obscured) becomes white, and clicking in that space actually clicks-through to the application (or desktop) that is behind it.

It appears to only happen to a single application at a time, and the effect disappears if the user pulls that application out of full screen mode (using the Windows-Arrow shortcuts, as the minimize, windowed, and close buttons at the top are no longer accessible). I've seen it in IE, Word, Excel, and Acrobat. The issue disappears with a reboot. I can probably count the number of times it's occurred on both hands in the last year, and I've never had a chance to really do much more in the way of testing. I dont believe there's any event log entries that appear in conjunction with it.

Our office is running all dell hardware (laptops and desktops of different flavors), on Windows 7 32/64bit, and the only thing that appears consistent between the users having the problem is the use of two monitors.

It started happening to just one user about a year ago (infrequently) and has recently been reported by 3-4 more users in the last couple months.

We've been users of AVG and Malwarebytes, and I dont suspect anything nefarious... just seems to be an irritating bug from the looks of it.

Anyone else run into this, or have a permanent fix? I've googled up a storm trying to find anything related to it, and came up empty.

Yeah, my work PC is Win8, this is affecting 5-6 other users in our office that are running Win7 32/64 bit.

I just had another report, and grabbed a screenshot (attached) of the issue. Closing the application (IE in this instance) and re-opening did not resolve it. So it's somehow tied into the way a specific app is rendering, until rebooting.
