The demo used to work fine with older Mesa versions such as 8, 9 series but with newer Mesa 10 the demo only shows black color. My guess is something is disabled in Mesa 10 by flags which are required by the demo. tested on the other hardwares as well, such as with nvidia quadro 600 where it works fine with nouveau and proprietry drivers. System: Ubuntu 13.10 linux 3.12.0-031200-generic Mesa 10.2.0-devel (master branch) xf86-video-intel 2.99.911 Intel GMA 4500MHD (device id: 2a42) Intel Sandybridge Mobile (device id: 0116)
Does it work if you force some specific GL version with: MESA_GL_VERSION_OVERRIDE=x.x ? (I don't know where to get "caps viewer", but when I've tested GpuTest, e.g. its geometry instantiation test works with Mesa only if one overrides GL version, and it doesn't matter which GL version you use...)
http://www.ozone3d.net/gpu_caps_viewer/ the demo does not require any MESA_GL_VERSION_OVERRIDE for my GMA 4500 since it uses only GL 2.1. But the situation is same for Sandy Bridge graphics
imamdxl8805, is there a linux version available and where is it?
no Linux version, you can run via WINE, here is the apitrace's trace file
trace file http://www.mediafire.com/download/59co5t84of34xgy/wine-preloader(3).trace
Created attachment 97013 [details] error log errors on console when running HDR, DoF and RadialBlur test on wine.
I've attached console log in case the errors ring any bells on anyone. For me it looks like initial framebuffer object creation fails and therefore everything fails with that fbo.
I've tried to bisect this, with origin/9.1 rendering is still fine but with origin/9.2 it breaks. It is not trivial to find what changes break this though, for me it looks like some patches backported to 9.2 are the ones, will dig some more.

Just to add, it can be also that something 'fixes' this for 9.1 but those patches are not in 9.2, there's these cases too.
I built mesa-10.0.0 and confirmed that the trace drew black. Mesa from today draws multiple spinning tori. I think this is fixed, but I don't know when it was fixed. Please reopen if you think it is not fixed.
