            Bug ID: 93110
           Summary: [NVE4] textureSize() and textureQueryLevels() uses a
                    texture bound during the previous draw call
           Product: Mesa
           Version: 10.5
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium

A small program to demonstrate the issue

It seems that a texture bound in the previous draw call is used by
textureSize() and textureQueryLevels() (instead of the currently bound
texture).

The attached program demonstrated the bug. When the program is built with
-DBROKEN, it incorrectly prints "width: 2.000000 height 2.000000 miplevels
2.000000" while the current texture is 512x256 with 4 miplevels.
