Also on Ubuntu 18.04 i7-4790 with Intel Integrated Graphic Card. I think this is not related to graphic card.
If you still want to use transparency from system theme, you can try following: 1. Uncheck "Use transparency from system theme" 2. "Check Use tranparent background" 3. Re-check "Use transparency from system theme" And the background will become stable with system theme transparency. I guess gnome terminal sometimes mistakenly checking the grayed out "Use transparent background" setting and disabled transparency, thus cause the flickering. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-terminal in Ubuntu. https://bugs.launchpad.net/bugs/1726262 Title: 17.10 - flickering overlay patterns in gnome-terminal To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-terminal/+bug/1726262/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
