https://bugzilla.kernel.org/show_bug.cgi?id=196125 Bug ID: 196125 Summary: [Regression] AMD Radeon RX 480 flickering on HDMI port with Linux 4.11.4 Product: Drivers Version: 2.5 Kernel Version: 4.11.4 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: contact@xxxxxxxxxxxxxxxxxx Regression: No Using a Sapphire AMD Radeon RX 480 Graphic Card with the amdgpu driver. Since a Linux Kernel upgrade from 4.10.6 to 4.11.4, I'm experiencing screen flickering (full black or white screen blinking) when the picture on the screen in changing (video, moving windows). There is no flickering when displaying a static picture. The flickering occurs when the screen (with a DVI connector) is connected to the Graphic Card's HDMI port. There is no flickering when the screen is plugged to one of the Radeon's Display ports (with a HDMI to Display port adapter). This flickering didn't occur with Kernel 4.10.6. $ cat /etc/fedora-release Fedora release 25 (Twenty Five) $ uname -a Linux amn 4.11.4-200.fc25.x86_64 #1 SMP Wed Jun 7 18:28:00 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
