Could Ralf Meyer please clarify: What exactly do you mean by flickering? I am experiencing a problem that could be described as flickering, but I can't tell whether this bug report is about the same thing or whether I should create a new bug report.
I am experiencing a regression in linux-image-generic-hwe-16.04 with Intel HD Graphics 530, starting in 4.13.0-43-generic, where some form of low-frequency temporal dithering has been enabled. This is causing a shimmering effect and visible dithering patterns. 1px borders in the UI can appear to have a "marching ants" effect. The effect is visible both under Xorg and in a virtual console (Ctrl+Alt+F1). Booting 4.13.0-41-generic eliminates the temporal dithering. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1747340 Title: flickering graphics with intel gfx card To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-hwe/+bug/1747340/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
