Thanks. I understand that the logs I provided do not conclusively prove that the crash was caused by the tiling extension.
However, during my investigation I found that the Ubuntu Tiling Assistant extension was enabled but reported an ERROR state: gnome-extensions info [[email protected]](mailto:tiling- [email protected]) showed: State: ERROR The GNOME Shell journal extracted from the crash report also contained messages such as: * "Trying to re-add keybinding 'toggle-tiling-popup'" * "Extension point conflict: there is already a status indicator for role tiling-assistant@leleat-on-github" and multiple stack traces referencing files from the Ubuntu Tiling Assistant extension. As a workaround, I disabled the extension: gnome-extensions disable [[email protected]](mailto:tiling- [email protected]) and re-enabled Mutter's native edge tiling: gsettings set org.gnome.mutter edge-tiling true After rebooting, the extension remained disabled and: gsettings get org.gnome.mutter edge-tiling returns: true Since applying this workaround, GNOME Shell has not crashed again and window snapping functionality continues to work through Mutter's built- in edge tiling. I cannot prove causation from the available logs, but there appears to be a correlation between the extension error/conflict and the GNOME Shell instability I was experiencing. For me, it works as explained, but I'm providing info just in case is helpful for fix some bug or help others. I can't provide any more file because, as I said, my whoopsie is void, even with sudo, it not seems to be a privileges thing, so can't see any ID. About the /var/crash, I just have: _opt_google_chrome_chrome.1000.crash, and _usr_bin_gnome-shell.1000.crash. No .update or more here. Please let me know if there is any additional information I can collect that would help determine whether this is a GNOME Shell/Mutter issue or an Ubuntu Tiling Assistant extension issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2155232 Title: GNOME Shell crashes when moving windows between monitors in a multi- display setup.
