Juce OpenGL performance

Here i’m again with some OpenGL problems :frowning:
Using last GIT branch with Visual Studio 2010 SP1 under Windows 7 SP1 i’ve got some strange Juce Demo behavioral. Attachments might be more coloreful against my words…
http://www.filedropper.com/juce and from Qt http://www.filedropper.com/qt.
Breifly: it is some lags with juce demo and espacially to text in it. At the same time Qt OpenGL “helloworld” project works just fine, and any other app that uses OpenGL library works fine too. WAIDW?! :oops:
P.S. captured by VLC, so it is also might be the best option to view it.
Thank you.
