Oh no, you seem to have installed graphics packages from the 'oibaf' PPA. That PPA is known to cause bugs like this and is unsupported.
Please remove the PPA from your system completely, and then report a new bug if the flickering persists. ** Changed in: kwin (Ubuntu) Status: New => Invalid ** Changed in: linux (Ubuntu) Status: New => Invalid ** Changed in: xorg-server (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/2003762 Title: [amdgpu] alienware aw3423dwf flickers at 165hz under linux only.
