Time by time, mainly during scrolling whole system freezes. Restart necessary.

[brubec]

This problem occures on all programs, which has a scroll button, such as Firefox, Google Chrome, Terminal a.s.o. It appears time by time, normally 5 minutes after starting the computer and mostly during using the scroll button. The bottom half of the program window is getting black and the system is freezing. Sometimes it occures also while doing nothing. In that case the computer is only freezing without black areas on the display. I use a Nvidia Geforce 8400 M.

[Georges Loriod (gldfree)]

removing nvidia proprietary driver solve this issue but that could only be temporary.

We are sorry that we do not always have the capacity to review all reported bugs in a timely manner. You reported this bug some time ago and there have been many changes in Ubuntu since that time.

Ubuntu 12.04 (precise) reached end-of-life on April 28, 2017.

Do you still see a problem related to the one that you reported using currently supported versions of Ubuntu and Firefox? Please let us know if you do otherwise this report can be left to expire in approximately 60 days time.

Thank you for helping make Ubuntu better.
