Public bug reported:
I have been having an issue with garbled graphics on an ASUS K50IJ
Laptop with Intel GMA X4500 integrated graphics.
It is a difficult bug to recreate in a timely fashion as it requires you
to be on the system for a decent amount of time (like an hour, sometimes
less). Usage scenario to recreate this bug: would be to gradually build
up to 10 Firefox or Google Chrome tabs. Minimize the applications, Open
a 4000x3000 pixel photo in GIMP, do some editing. After using the
computer for a while, go to the launcher and click Firefox or Chrome.
Close Firefox or Chrome and then close GIMP. Firefox will take a while
to close and while the hard drive is loading, the screen will suddenly
become garbled.
I've been a user of Ubuntu since version 6.06 (Dapper Drake) and have
been using it exclusively on this laptop since version 12.04. I have not
had this issue until 14.04.
The temporary workaround is to log out and log back in, after which the
graphics are back to normal. I also checked to see if it was a memory
issue but System Monitor does not appear to display such an issue.
