Description of problem: When running Gimp under Gnome/Wayland the function to take a screenshot does not work. Version-Release number of selected component (if applicable): Gimp 2.8.18 How reproducible: * Always broken (makes an all-black image). * Infrequently will crash the entire Wayland session, killing all applications. Steps to Reproduce: 1. Be sure you've logged into a Wayland session. 2. Start Gimp and then select the menu File > Create > Screenshot... 3. Click the "Snap" button to attempt to take a screenshot. If taking a shot of a single window rather than the entire display you are supposed to click the mouse inside the target window. Actual results: The newly created image file will have the correct dimensions but will be entirely black. Expected results: The image file should be a copy of what was displayed. Additional info: I know this is in general a "known issue" with Wayland, but I've not seen this specific mention of a Gimp feature being mentioned. Also it this can't be fixed it may be preferable to hide the Create/Screenshot menu choice when running Gimp under Wayland. Other interesting behavior... when taking a window screenshot, the cross-hairs cursor used to select the target window can only select those windows that run under the Meta X11 class, and not the Wayland class (e.g., can't click on say a gnome-terminal).
Created attachment 1224178 [details] crash log from journctl This is the output from journalctl (without the timestamps and hostnames) after the entire Wayland session crashed when trying to take a Gimp screenshot. Note as invalid event timestamps are mentioned, I did check that the system chrony (ntp) service is working and the system is synced up to an NTP clock.
As for the occasional crash of Wayland itself. I don't know if this is the same bug or not. But I was able to make it happen at least three times by doing nothing other than taking screenshots from the Gimp application (of course getting black images when it didn't crash).
