Bug Description
Binary package hint: gnome-terminal
After upgrading to Feisty (7.04) I began having problems with gnome-terminal's display becoming corrupted. It is conceivable that this is instead a problem with my X server, but given that no other application or terminal has been exhibiting similar problems I expect it is probably something particular to how gnome-terminal is written. The most frequent problem is that when returning to a gnome-terminal window after switching virtual desktops there will be graphical garbage in terminal window. In particular the garbage often takes the form of bits of graphics that were being displayed by other software on other virtual desktops. Sometimes the graphics even comes from software that is no longer running, so I suspect that somehow gnome-terminal is reusing video memory but not properly clearing it first. I will also frequently run into problems when loading a large text file with less, and text will become overwritten with other text when scrolling, or black blocks of inverted text.
I just spent a few minutes trying to reproduce the problem in a way that so that I could obtain a screenshot, but did not succeed. I'll try to amend this bug report as soon as I can capture something.
My graphics chipset is
ATI Technologies, Inc. Radeon Mobility M6 LY [Radeon Mobility 9000]
and I'm using the "radeon" driver module.
Probably, it's at least an interaction between gnome-terminal and your X driver; where the bug lies is hard to say. I'm adding xserver- xorg-video- ati so that between the two, perhaps we can find the bug in one or both. Perhaps its a duplicate of bug 34435, though AFAICT the symptoms are different from that bug and its duplicates. However, it mentions problems with the XRENDER extension, used via Cairo in most apps, which gnome-terminal also uses.
Are you able to reproduce this problem in xfce4-terminal (which shares the same library code for the terminal emulation widget as gnome-terminal)?
