There are a bunch of piglit fast clear tests that regressed on SI, for
example ./bin/ext_framebuffer_multisample-fast-clear single-sample.
The problem is that a texture is bound as a framebuffer, cleared, and
then rendered from in a loop that loops through different clear colors.
The texture is never rebound during all this, so the change to
tex->dirty_level_mask during fast clear was not taken into account
when checking for compressed textures.
I have considered simply reverting the problematic commit. However,
I think this solution is better. It does require looping through all
bound textures after a fast clear, but the alternative would require
visiting more textures needless on every draw. Draws are much more
common than clears.
Note that the rendering feedback loop rules do not apply here, because
the framebuffer binding is changed between the glClear and the draw
that samples from the texture that was cleared.

File: docs/README.WIN32 Last updated: 21 June 2013 Quick Start ----- ----- Windows drivers are build with SCons. Makefiles or Visual Studio projects are no longer shipped or supported. Run scons libgl-gdi to build gallium based GDI driver. This will work both with MSVS or Mingw. Windows Drivers ------- ------- At this time, only the gallium GDI driver is known to work. Source code also exists in the tree for other drivers in src/mesa/drivers/windows, but the status of this code is unknown. Recipe ------ Building on windows requires several open-source packages. These are steps that work as of this writing. - install python 2.7 - install scons (latest) - install mingw, flex, and bison - install pywin32 from here: http://www.lfd.uci.edu/~gohlke/pythonlibs get pywin32-218.4.win-amd64-py2.7.exe - install git - download mesa from git see https://www.mesa3d.org/repository.html - run scons General ------- After building, you can copy the above DLL files to a place in your PATH such as $SystemRoot/SYSTEM32. If you don't like putting things in a system directory, place them in the same directory as the executable(s). Be careful about accidentially overwriting files of the same name in the SYSTEM32 directory. The DLL files are built so that the external entry points use the stdcall calling convention. Static LIB files are not built. The LIB files that are built with are the linker import files associated with the DLL files. The si-glu sources are used to build the GLU libs. This was done mainly to get the better tessellator code. If you have a Windows-related build problem or question, please post to the mesa-dev or mesa-users list.
