Description of problem: After the upgrades from kernel-4.3.4-300.fc23.x86_64 I've started experiencing visual problems using gnome desktop. Version-Release number of selected component (if applicable): The following kernels manifest the problems: i) kernel-4.3.5-300.fc23.x86_64 ii) kernel-4.4.2-301.fc23.x86_64 How reproducible: 100% Steps to Reproduce: 1. boot into the above kernels, login into GNOME session (Either wayland or non-wayland) 2. open terminal, or a browser (firefox/google-chrome, whatever) 3. Actual results: a) mouse cursor disappearing: only visible in gnome top bar or in the notification bottom applet's area b) flicker: b.1) if you're on kernel-4.4.2 - sometimes switching applications in full screen causes screen to run and flip-rotate as if out of sync on the old CRT display when vertical sync was mismatching - the image would scroll-rotate vertically, here it is happening horizontally b.2) on any affected kernel the flickering artifacts appear - on display Expected results: a) visible mouse cursor b) no flicker, no image rotation Additional info: My hardware is: Lenovo ThinkPad T450 ----8<----8<----8<----8<----8<----8<----8<---- [root@localhost ~]# lspci 00:00.0 Host bridge: Intel Corporation Broadwell-U Host Bridge -OPI (rev 09) 00:02.0 VGA compatible controller: Intel Corporation Broadwell-U Integrated Graphics (rev 09) 00:03.0 Audio device: Intel Corporation Broadwell-U Audio Controller (rev 09) 00:14.0 USB controller: Intel Corporation Wildcat Point-LP USB xHCI Controller (rev 03) 00:16.0 Communication controller: Intel Corporation Wildcat Point-LP MEI Controller #1 (rev 03) 00:19.0 Ethernet controller: Intel Corporation Ethernet Connection (3) I218-LM (rev 03) 00:1b.0 Audio device: Intel Corporation Wildcat Point-LP High Definition Audio Controller (rev 03) 00:1c.0 PCI bridge: Intel Corporation Wildcat Point-LP PCI Express Root Port #6 (rev e3) 00:1c.1 PCI bridge: Intel Corporation Wildcat Point-LP PCI Express Root Port #3 (rev e3) 00:1d.0 USB controller: Intel Corporation Wildcat Point-LP USB EHCI Controller (rev 03) 00:1f.0 ISA bridge: Intel Corporation Wildcat Point-LP LPC Controller (rev 03) 00:1f.2 SATA controller: Intel Corporation Wildcat Point-LP SATA Controller [AHCI Mode] (rev 03) 00:1f.3 SMBus: Intel Corporation Wildcat Point-LP SMBus Controller (rev 03) 00:1f.6 Signal processing controller: Intel Corporation Wildcat Point-LP Thermal Management Controller (rev 03) 02:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd.

This message is a reminder that Fedora 23 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 23. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '23'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 23 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 23 changed to end-of-life (EOL) status on 2016-12-20. Fedora 23 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
