Default rendering artifacts with OpenGL and Xcursor extension (XFree 4.3)

I'm using nVidia driver version 1.0.4496 together with XFree86 4.3.0 and Xcursor theme that uses alpha transparency (practically any non-core one, e.g. set XCURSOR_THEME=whiteglass).
I'm getting very ugly artifacts with all OpenGL applications: if the cursor is over an OpenGL window and the part of the window under the cursor is redrawn, a rectangular area around the cursor is redrawn by a filled monocolor rectangle.

It is particularly well visible in Blender where the artifacts generated by virtually any move of the mouse, e.g. over the menu, are so severe that the app is unusable.

Unfortunately there's no easy workaround because setting XCURSOR_CORE=true has effect on all cursors except the default one, probably due to unrelated bug in XFree itself.

Default Blender + rendering artefacts

I got the same rectangular artefacts in Blender (with a RIVA TNT2 32Mb). I tried to solve it several times by editing XF86Config-4 options, but was not succesful.
Now I've got a GeForce FX 5200 128Mb. In Knoppix 3.3 I installed the libxcursor1 package, after that all the OpenGL applications (Blender, Innovation3d) worked perfect.

This may not be related or helpful, but have you forced FSAA off?

TNT2 didn't have FSAA... Besides, FSAA would hardly affect such thing as proper hiding and re-showing of cursor in the driver...

Quite right on the card, I overlooked that. On the driver, anything drawn to screen under FSAA could be affected, why would the mouse driver be any different? But in this case it has nothing to do with it.

(blender has big issues with AA, the main reason it occured to me to mention this)
