Confirming that this issue does occur with Ubuntu 18.04.1, i7 3770, with AMD Radeon RX 480, using AMDGPU. I'm also using the kernel ppa 4.17 from June 4th, so I can keep AMDGPU DC enabled and use my primary monitor's DVI-D dual link connection to support 120Hz refresh rate.
I can also confirm that unchecking "Use transparency from system theme", checking "Use transparent background", and re-checking "Use transparency from system theme", results in a stable background. Perhaps "Use transparent background" should check itself if the system theme employs transparency? -- 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/1726262 Title: 17.10 - flickering overlay patterns in gnome-terminal Status in gnome-terminal package in Ubuntu: Confirmed Bug description: Clean install of Ubuntu 17.10. For gnome-terminal select color-scheme "black on light yellow". Overlay partly with e.g. Chrome (Browser) or Geany (editor). Then the border shadow of the e.g. Geany produces flickering extended shadows in the gnome-terminal. Foto with the extended shadows is attached. This bug was introduced with 17.10. This flickering didn't appear in 17.04, 16.10, 16.04... Working as a developer with several open terminal windows on the desktop, this produces a disturbing desktop environment and mitigated by covering not used terminal windows complete with other apps. Haven't reproduced with other apps than gnome-terminal.
