DRI PRIME: black window on Intel + Radeon Whistler

When I launch DRI_PRIME=1 glxgears, I get only black window. However, with XRender-based compositing (KWin), everything works fine.
Fullscreen applications work without compositing.
glxgears prints framerate to console, dmesg doesn't contain any errors.
Happens with: Mesa 9.1.6 and Mesa Mesa 9.2.0 (git-9586f4de) Xorg server 1.13.4 and Xorg server 188.8.131.522 I tried both SNA and UXA for Intel driver, no difference.

There are also problems with KWin OpenGL compositing. However, maybe it's KWin bugs:
- Black window for windowed applications. However, if I resize the window, the application starts to render correctly.
- Black screen for fullscreen applications, unless I enable unredirection or disable compositing. Or, if I switch to another window and return back, the application starts to render correctly too.
