System Information
Win 7 64bit
Mobility radeon 5650
Catalyst driver 12.10

Blender Version
Broken: blender-2.73-testbuild1-win64
Worked: Official 2.72b

Short description of error
Sun shadows in GLSL view do not look right. It appears the whole of the shadow map frustrum is filled with the shaded value. I'm attaching a comparison screenshots from the viewport. The bug happens with simple and variance shadow map style.

I do have older drivers, but everything worked well so far. If other cards work properly I could test with a newer driver version.

Just a note here, we had an issue there but was fixed 1-2 weeks ago. If this is happening on latest builds from builder.blender.org we really need a test file to reproduce.

I'm attaching a test file and a screenshot of how it looks like on my computer. It happens with a very simple setup already, default cube, plane and a sun lamp with shadows enabled.

I tested the file in the following blender versions with the same result.
blender-2.73-testbuild1-win64
blender-2.72-7234153-win64

Cannot confirm here... Smelling a driver issue, or something Windows related

Cannot confirm here either I'm afraid. Can you try with factory settings? Also, can you attach a system_info.txt file generated from blender (see http://blender.org/manual/vitals/help.html#diagnostics-options)?

Factory settings give the same result. I'm attaching the system_info file.
system-info.txt

I'll see if I can test this on another OS tomorrow. Or if possible get the latest drivers installed (tricky due to manufacturer limiting which drivers can be installed).

Alright, I can confirm on the MacOS trashcan I'll see if I can fix this

Ok, I tested blender-2.72-7234153-linux-glibc211-x86_64 on Linux Mint 17 with default open source drivers and everything displays fine. It appears the issue is indeed with windows/driver.
