Comment 14 for bug 136838

For now this problem only exists with (obviously unsupported) "foreign" software (NVidia driver installed manually).
From a pure Ubuntu point of view it cannot be reproduced because of other problems of the current nvidia-glx-new package (see Bug #98641).
Therefore I set this bug to invalid and assign it to me.
Whenever untill nvidia-glx-new is fixed, I will retest the situation with a pure Ubuntu configuration and then decide either to close or to re-open this bug.
