Comment 5 for bug 1294762

Nouveau still seems no to support the GTS 250M and only runs in a 640sh resolution and every thing seems to be software rendered. I can't clearly state if the blur effect still applies due to the over all low resolution, but I think the described problem isn't applying in this case.

Furthermore the problem comes in sporadically under the proprietary drivers. I couldn't find the trigger for the wrong display behavior.
