Similar symptoms as above: frequently switching from gnome-terminal to Firefox causes gnome-terminal to scroll very slowly (takes one or two seconds to scroll a single line). Single monitor display, nVidia GeForce 8400, driver version: 304.43, Ubuntu 12.10 64bit.
Tried to figure out when and why that happens and here are some scenarios: - happens with every libvte based terminal - happens with xterm and rxvt-unicode if an xft font is used for display - does _not_ happen with xterm and rxvt-unicode if a bitmapped xorg core font is used - happens with every libvte based terminal if system wide font hinting is set to slight and font anti-aliasing is set to none (in this case fonts will look the same as a bitmapped xorg core font) As you can see, even if the system wide setting is set to look the same as a bitmapped font, it does behave differently in this case. Could this be related to some font rendering performance? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-terminal in Ubuntu. https://bugs.launchpad.net/bugs/850649 Title: gnome-terminal extremely slow and display buggy Status in “gnome-terminal” package in Ubuntu: Confirmed Bug description: After the update to oneiric the gnome-terminal appears to be slow and display is sometimes buggy: * changing between windows and tabs is slow although other applications (like chromium) are not affected * sometimes the display is not updated and some parts (exactly on character box boundaries) of the terminal just show the background ProblemType: Bug DistroRelease: Ubuntu 11.10 Package: gnome-terminal 3.0.1-0ubuntu3 ProcVersionSignature: Ubuntu 3.0.0-11.18-generic 3.0.4 Uname: Linux 3.0.0-11-generic x86_64 NonfreeKernelModules: nvidia ApportVersion: 1.23-0ubuntu1 Architecture: amd64 Date: Thu Sep 15 08:28:30 2011 EcryptfsInUse: Yes ExecutablePath: /usr/bin/gnome-terminal InstallationMedia: Ubuntu 10.10 "Maverick Meerkat" - Release amd64 (20101007) SourcePackage: gnome-terminal UpgradeStatus: Upgraded to oneiric on 2011-09-01 (13 days ago) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-terminal/+bug/850649/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
