[sldev] Display corruption when switching Anisotropic/Antialiasing hardware options

[Ann Otoole]

nVidia 8500GT on Vista64/4GB/Quad Core here and no repro. I went to 16x antialiasing with ansiotropc on and nothing unexpected happened except it appeared to change resolution more gracefully than v1.22.

Subject: [sldev] Display corruption when switching Anisotropic/Antialiasing hardware options

At least snowglobe (1.0.0.0.2435) doesn't crash!  I tried repoing on
1.23_rc4, but it crashed instead of corrupting...

The effect is the same no matter what skin I use: The display turns
whitish, all text characters turn into rectangles, skin borders go
away, etc.

Restarting Snowglobe fixes the issue.

Can anyone else repo?  The steps are as follows:
1: Start Snowglobe (don't log in)
2: Goto Edit->Preferences
3: Select the Graphics tab
4: Pres the "Hardware Options" button
5: Select the Anisotropic Filtering checkbox, and set Antialiasing to
4x or more.

If at first it doesn't corrupt, try other AA values.

I am running Gentoo with KDE4.2.4:
