Information distilled from VWR-6343 (a JIRA grown too muddy to be useful). From Foock Yue: I am having terrible trouble with the new 1.20 RC, the client seems to absolutely destabilise my nvidia drivers. First of all i see small freezes, then these freezes start becoming more pronounced, and then the screen starts blanking once every 10 seconds (with the vista "the display driver stopped responding and has recovered" notice).. and then this happens every 5 seconds.. and then the system hangs. -------
