This message is a reminder that Fedora 25 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 25. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 '25'. 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 25 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 25 changed to end-of-life (EOL) status on 2017-12-12. Fedora 25 is no longer maintained, which means that it will not receive any further security or bug fix updates.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. |
Created attachment 1227939 [details] Source code for minimal love2d test "game" to reproduce the issue Description of problem: Minimal love2d example with multiple canvases misbehaves and flickers with Gnome3/Wayland/Intel(Skylake). The same example works perfectly fine with X11. I attached the source code for testing. I would just like to say this is not a purely cosmetic lab-crafted issue, I made this example code after having huge flickering issues with an actual game project of mine. which currently would suffer from those problems in the default configuration as Fedora 25 now ships with, unless this issue is fixed. Also I don't know of any good workaround except tell users to run an X11 session, which is a somewhat sub-optimal situation especially for games who may also target a less technically inclined audience. Version-Release number of selected component (if applicable): GNOME Shell 3.22.2 mutter 3.22.2 love2d 0.10.2 Mesa 12.0.3 How reproducible: 100% (may take a minute of waiting and causing some additional system load, see below) Steps to Reproduce: 1. Download attached source code and place into file named "main.lua" in new empty directory 2. Install love2d (dnf install love) 3. Change into directory with main.lua 4. Type this to launch program: love . Actual results: When running a GNOME Wayland session (Fedora 25 default), the window flickers to black (every 5-30 seconds). The problem appears more often under system load and when a video is playing in a web browser at the same time. In a GNOME X11 session, it displays a perfect white window all the time. Expected results: Window is white under all conditions, including when running with wayland. Additional info:
