Description of problem: The VNC server sends the same three frames when DRI3 is enabled on integrated 1st(?)-gen Intel HD Graphics card. This happens for both x11vnc and x0vncserver. Version-Release number of selected component (if applicable): xorg-x11-drv-intel-2.99.917-20.20160119.fc23.x86_64 [1] How reproducible: Always Steps to Reproduce: 1. Run x11vnc 2. Connect to system using vnc client Actual results: Same three frames are repeated in VNC client Expected results: VNC client should show what's actually on the screen Additional info: This doesn't happen on newer systems running Intel HD Graphics 2500, so it seems to be something specific to this particular integrated chipset. As a temporary workaround, I've downgraded the system to xorg-x11-drv-intel-2.99.917-16.20150729.fc23.x86_64, which doesn't have DRI3 enabled, and it works fine. Also, FWIW, the login screen (under LightDM) works just fine. The frames don't start repeating until gnome-shell actually launches. [1] rebuilt from koji because we have other systems running the same disk image that require DRI3 for hardware acceleration when multiple video cards are in use.

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 It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 Fedora 23 is no longer maintained, which means that it will not receive any further security or bug fix updates.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.
