Hi fellow archers! This is my first post to this mailing list, so please excuse my behavior if I have picked the wrong list =) For a couple of months now, I have been experiencing occasional "flickering" in my terminal emulator (urxvt, but also happens with xterm, roxterm and gnome-terminal). There are several forum threads on the same issue: https://bbs.archlinux.org/viewtopic.php?id=118648 https://bbs.archlinux.org/viewtopic.php?id=117202 https://bbs.archlinux.org/viewtopic.php?id=117423 The latter seems to be the biggest one... The problem is that every now and then, the terminal seems to "forget" to draw some of the text on the screen, leaving a mangled output consisting of some stale text cells (as in the character that was previously in that position is still visible) and some empty cells (the previous character was a space, and the new character was not printed). The problem seems to occur sporadically, but happens often enough to be a real nuissance. Highlighting any text in the terminal window causes the text to be immediately corrected. The problem also appears when using vim or terminal-based emacs (i.e. curses interfaces). Seems the problem is quite widespread, and affects both nVidia, AMD/ATI and Intel graphics drivers.. A bug in X perhaps? Could someone with a bit more know-how than me please have a look? Any help is greatly appreciated, Jon

Any help is greatly appreciated, Jon Sounds like the problem I've been having with atris [1] and scummvm [2]. Try those, see if you have any redraw problems (switch to fullscreen in atris; just start `scummvm` and move around the mouse). Also try linux 2.6.38.6 [3]. That one doesn't have the problem, the first 2.6.39 does.
My graphics card is intel 965gm. [1] https://aur.archlinux.org/packages.php?ID=7671 [2] https://www.archlinux.org/packages/?q=scummvm [3] http://schlunix.org/archlinux/core/os/ -- cantabile "Jayne is a girl's name." -- River

That said, I just switched to the open-source nvidia drivers to see if that would help, and I haven't seen any X terminal problems here yet, so perhaps the open-source drivers don't have the problem? Switching from proprietary to open-source nvidia drivers shouldn't be considered a fix the problem though, since some might require the extra features of the proprietary ones. Besides, it can't really be solely the fault of the driver since people with Intel graphics chips have the same problem? Jon

I've reported the similar problem with my I965GM card and 2.6.38 and 2.6.39 kernels. However it happens only with xterm and rxvt, but never with GTK-based roxterm and Terminal. Yesterday I've installed 3.0 kernel, and so far everything works fine. -- Cheers, Sergey
I've had the same issue on gnome-terminal after using ffmpeg. (kernel
2.6.39; nvidia driver on 9800 GTX)

My software never contains bugs, it just develops random features.
