--- Comment #31 from Roderick Colenbrander thunderbird2k@gmail.com 2010-07-05 13:49:40 --- A month ago I submitted a bug for a related issue to Nvidia (a test case is here http://pastebin.com/5AAKHpW6). It was about blitting from a multisampled FBO to a non-multisampled window/fbo. The issue appears to be the same (well in the Nvidia drivers it triggers the same code path). If I disable multisampling in my test and enable multisampling in nvidia-settings, you can see the same bug as here but blitting also fails without any flipping.
Nvidia is working on fixing the issues but some parts seem trivial but some of the issues require some more changes in their driver. I have no idea when we will see a fix but I guess it will take a few months before it enters a stable release.
