well it had to happen eventually (i forgot to keep the battery charged up) so the opportunity to restart arrived - changed to DRI=3 and, ta-daaa, problem's gone.
... or, at least, carrying out the previously 100%-repeatable test (resize of a window under fvwm2) is no longer 100% repeatable. i'll run some more programs that are known to be problematic (with DRI2) over the next few days, and report back. l. _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/mesa-dev
