[Bf-committers] Does processing become slow in Textured Solid?

[PerfectionCat]

Developers, hello.

The phenomenon that processing became slow occurred as having frozen up in 3D View when I set Shading with some blend files in Textured Solid.
I open the same blend file in 2.63, 2.49b and changed Shading, but processing did not become slow.
The error is not recorded to a console screen.

Use environment.
