I migrated from Windows XP to Windows 7 Ultimate 64 bits and I encountered a display issue in some Microsoft/Windows Live products that did not exist in Windows XP (the same programs do not have this kind of problem on Windows XP).
That issue appears in:
- Windows Live 2011 products (e.g. Messenger and Movie Maker - not with older versions)
- Some newer Microsoft products (e.g. Microsoft Visual C++ 2010 Express - not 2005 version; I don't know about 2008)
It affects some image and text elements on these programs, distorting them.
It is so difficult to explain that graphical issue, so I upload an edited image showing one screenshot for each mentioned software above. I did not reduce image quality of screenshots to show the issue, that appears to be some pixels drawn in wrong places, but near the right ones (I put some red arrows near distortion places):
(below it was reduced to Super User question width, but you can see it in http://i.stack.imgur.com/bXiBR.png . imgur reduced its quality a little, I think)
It is not:
- Wrong installation issue: I installed it four times (once I installed as 32 bits) and the problem repeated, and I did it formatting old installation.
- Windows Update issue: all these issues occur since Windows 7 installation and I've already installed all last updates.
- Windows Update issue: I've already installed all last updates.
- DirectX issue: I installed the newer one, and both, newer and older, show the same issue.
- Driver problem: I installed the newer graphical drivers (monitor, adapter...), and both, older and newer drivers, show the same issue.
- Incompatibility with other programs: I installed only Windows 7 + Windows Live Messenger 2011 and the problem appeared.
- User account: it occurs with any user of any kind (common or admin).
- Clear Type: I already tested disabling or adjusting Clear Type, but the issue did not disappear.
- Monitor: I connected external monitor and the same problem occurs.
- A problem that appears with other OS: I tested Windows XP, Ubuntu 32 and 64-bits, Slax, Android-x86... in that machine, but only Windows 7 show that issue...
- .NET: I think the distorted components of mentioned programs in some way use that framework, but I have already executed some other programs that use .NET and they functioned (I don't know about .NET versions...). I installed all .NET frameworks (1.1 SP1, 2.0 SP2, 3.0 SP2, 3.5 SP1 and 4.0), but no effects.
- A hardware problem: well, I "heard" in in ternet something about Bios update for some strange cases in Windows 7, but the manufacturers of that motherboard and notebook have never provided a Bios update...
- DirectX: I heard about problems with early versions of Windows Live products and DirectX.
- SISM672 Northbridge and SiS968 Southbridge Chipsets: In this article http://nano-universo.blogspot.com/2010/05/chipset-sism672-sis-672-968.html (in Portuguese), author says that the real performance of these chipsets is about 16MB video RAM in Windows 7 instead of nominal 256MB (it's a reason for some users to abandon W7 and downgrade to WXP). Also it affects games with Direct3D resources...
