Hello,
I seem to be experiencing screen tearing within the desktop, but I think it's only in Adobe Reader XI. For instance, while I'm scrolling in a pdf file (with just a white background and black text), it seems like the screen tears in a similar manner to games without vsync on. I'm not sure if this happens outside of pdf files, as it's a bit hard to see sometimes while, say, browsing the web. Any thoughts? I have Windows 8 if that matters. Thank you.
