Created attachment 1538940 [details] screenshot missing window content Description of problem: Screenshot of window (alt+prtsc) produces image of appropriate size and title bar, but content of window is transparent. firefox-wayland-65.0.1-1.fc29.x86_64 How reproducible: Consistent Steps to Reproduce: 1. Open firefox-wayland 2. Trigger Gnome screenshot active window with alt+prtsc Actual results: Transparent area where window content is expected. Expected results: Screenshot of window with content. Additional info: Does not affect non-wayland firefox. User selection screenshot (shift+prtsc) is able to capture the window content.
Firefox renders its content to subsurface attached to main window which can cause this.
This is an old bug in Gtk/Wayland/[some underlying graphics library] and affects other applications as well such as gnome-maps (see bug #1384560 and upstream bug https://gitlab.gnome.org/GNOME/gnome-maps/issues/156). Also present on Fedora 29. Another workaround is taking a screenshot of the whole desktop (PrtScr key).
This message is a reminder that Fedora 29 is nearing its end of life. Fedora will stop maintaining and issuing updates for Fedora 29 on 2019-11-26. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 '29'. 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 29 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.
Still happening with F30
Should be fixed in F31.
WFM, Firefox 70 / F31.
