Re: [osg-users] Windows 7 Aero Color Scheme issue
Hi Magnus, Not sure about the answer to your question. But I believe this to be fixed in the latest NVidia Beta driver(well for my single screen anyway). I did look at the code and my brain went numb trying to find a fix. Might be worth trying the latest beta drivers see if it still occurs?

Re: [osg-users] Windows 7 Aero Color Scheme issue
Hi Guys, Have you seen last post from Farshid Lashkari in Re: [osg-users] Problem with samples thread ? Start Quote I've also been experiencing the fullscreen issue with nVidia cards on Windows 7. Just wanted to let you know that I found a workaround. When creating the OpenGL context, I changed the swap method from WGL_SWAP_EXCHANGE_ARB to WGL_SWAP_COPY_ARB. This completely solved the issue for me. Hopefully nVidia will fix their drivers in a future release. Farshid End Quote IMHO He has found the workaround and but also the source of the problem. I just checked his solution and it simply works. So I think that with Aero DWM not having front buffer but internal Direct3D texture, its quite understandable why COPY works better than EXCHANGE. Its hard to understand though why NvIdia drivers suggest EXCHANGE in ChoosePixelFormat when it does not work correctly. Btw I checked with DescribePixelFormat if the returned PixelFormat is compatible with PFD_SUPPORTS_COMPOSITION . And yes, returned description structure reports this compatibility. So this whole issue looks weird and definitely points to the drivers as the source of the problem. The drivers have the option to return PixelFormat with SWAP_COPY method but it keeps returning SWAP_EXCHANGE.

[osg-users] Windows 7 Aero Color Scheme issue
I've been working with osgprender, ran into a camera issue and am trying some things to see if I can work out a solution. As part of that, I found the --screen option in the viewer and set it to -- screen 0. While debugging it exhibits some strange behavior on my dual screen nVidia setup. 1. When starting from the debugger, the image will appear for a moment, then vanish with --screen 0 but not with --screen 1. With --screen 1 the image shows up and stays up, with --screen 0 I have to use Alt tab to find the window to get it to redisplay. 2. When starting from the debugger, with --screen 0, Win7 will pop up a message that says the color scheme has been changed because this application is NOT compatible with Aero. When running with --screen 1, this doesn't happen, no error message appears. 3. When I don't use the --screen option, it uses both screens just fine, and there is no warning message. In both cases, the program appears to work just fine, except for those two quirks. I'm not sure if the bug is osg, opengl, or nvidia drivers OSG 2.8.2 Win7 Enterprise 64bit nVidia details: NVIDIA System Information report created on: 12/01/2009 10:03:51 [Display] Processor:Intel(R) Core(TM) i7 CPU 920 @ 2.67GHz (2665 MHz) Operating System: Windows 7 Enterprise, 64-bit DirectX version: 11.0 GPU processor:GeForce 9600 GT Driver version: 191.07 Stream processors:64 Core clock: 725 MHz Shader clock: 1850 MHz Memory clock: 975 MHz (1950 MHz data rate) Memory interface: 256-bit Total available graphics memory: 3327 MB Dedicated video memory: 512 MB System video memory: 0 MB Shared system memory: 2815 MB Video BIOS version: 62.94.11.00.14 IRQ: 16 Bus: PCI Express x16 Gen2 [Components] nvCpl.cpl 2.7.170.15 NVIDIA Control Panel Applet nvCplUI.exe 2.7.170.15 NVIDIA Control Panel nvWSS.dll 8.16.11.9107NVIDIA Workstation Server nvViTvS.dll 8.16.11.9107NVIDIA Video and TV Server NVSTVIEW.EXE 7.16.11.9107NVIDIA GeForce 3D Vision NVSTTEST.EXE 7.16.11.9107NVIDIA 3D Vision Test Application NVSTRES.DLL 7.16.11.9107NVIDIA 3D Vision Module (4743138) NVMCTRAY.DLL 8.16.11.9107NVIDIA Media Center Library nvDispS.dll 8.16.11.9107NVIDIA Display Server NVCPL.DLL 8.16.11.9107NVIDIA Compatible Windows7 Display driver, Version 191.07 PhysX 09.09.0814 NVIDIA PhysX NVCUDA.DLL8.16.11.9107NVIDIA CUDA 2.3 driver nvGameS.dll 8.16.11.9107NVIDIA 3D Settings Server -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=20674#20674 Attachments: http://forum.openscenegraph.org//files/capture_170.png ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

I reported this behavior a while ago (probably about 2 years ago - check the archives) on Windows Vista. No one (including me) ever had the inclination to try and find the source of the problem... I've always assumed it was some weird Vista quirk. Now we can call it a weird Vista/7 quirk :-) It's not really that problematic, just a little irritating. I always start up fullscreen OSG applications on screen 1 anyways. But if it irritates you enough, you could want to scratch the itch and investigate further...
