My thoughts too. Looks like I'm sticking to 8.4 for a while. *sigh*. I was looking forward to this update, too - wine keeps failing with literally every directx app I care to try (it didn't with my old nvidia card), and I was hoping a driver update would fix it.
This is what I get for rampant fanboyism, I guess . I only bought ATI because they'd been bought by AMD, and they were doing the open-source thing. If I'd thought on it more, I'd have stuck to nvidia for a year or two more.
If you have examples of DX apps which work with wine on another card but not with our current driver can you let us know ?
Sure. The main example is the game "audiosurf". Other ones that don't work are NWN2 (not tested with the old nvidia card), the DXDiag 3D acceleration test(!) (with all the native DirectX9 stuff installed).
Here's what audiosurf says (with 8.4 drivers):
fixme:d3d:test_pbo_functionality >>>>>>>>>>>>>>>>> GL_INVALID_OPERATION (0x502) from Loading the PBO test texture
@ ../../../dlls/wined3d/directx.c / 3462
fixme:d3d:IWineD3DDeviceImpl_CreateQuery (0x13e910) Unhandled query type 4
wine: Unhandled page fault on execute access to 0x7c044b28 at address 0x7c044b28 (thread 000b), starting debugger...
I have a 10GB full-debug-run-log of what happens to NWN2... it's not exactly fascinating, mind.
Oh, and while I'm on the subject, fgl_glxgears -fbo hardlocks the computer (again, 8.4).
1- VLC still crashes with OpenGL output, throws this message:
 main private error: option glx-shm does not exist
libGL error: drmGetMagic failed
libGL error: reverting to (slow) indirect rendering

2- Scrambling video output bug with VideoOverlay option turned on in xorg.conf and XVideo output was partially resolved. Now it only happens rarely in fullscreen, but in windowed video playback, it is still seen.
