I have this bug also. I have an i7 6700 and use the internal video.
Only happened recently. And X keeps crashing with metacity (& others) so I've moved to xfce which has only crashed once in past three days, gnome was crashing frequently, typically when pressing mouse button on libreoffice or VirtualBox. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-ati in Ubuntu. https://bugs.launchpad.net/bugs/1558269 Title: font glyph corruption on dialog box (libreoffice plasma 5.5.4 radeon) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/1558269/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
