** Description changed: [ Impact ] Unable to perform Drag and Drop using from X11 applications running on XWayland to native Wayland applications. A set of applications that do not support Wayland and thus must use X11 on a Wayland desktop is commonly comprised of legacy proprietary apps, Java-based apps, and Electron-based apps. Those applications would be unable to drag-and-drop to the rest of the desktop. Here's the upstream bug report: https://gitlab.gnome.org/GNOME/mutter/-/issues/3511 [ Test Plan ] 1. Log-in to a GNOME Wayland desktop session 2. Open Terminal - 3. Run `GDK_BACKEND=x11 gnome-calculator` - + this forces the Calculator app to run in X11 mode, - + as if it were one of the legacy apps that do not support Wayland natively - 4. Position Calculator and Terminal side by side - 5. Type something on the Calculator app + 3. Run `GDK_BACKEND=x11 gnome-text-editor` + + this forces the Text Editor app to run in X11 mode, + + as if it were one of the legacy apps that do not support Wayland natively + 4. Position Text Editor and Terminal side by side + 5. Type something in the Text Editor window 6. Select the text 7. Drag and drop it into the Terminal window 8. Verify that the text was inserted in the terminal [ Where problems could occur ] mutter is the component of GNOME driving the screen and inputs, and thus is a critical component of Ubuntu Desktop. The patch only touches the XWayland drag&drop code, which was already not working. Regressions could manifest with the user being suddenly logged-out in the case that GNOME Shell has crashed because of a bug introduced by the new patch. [ Other info ] --- Alexander zvegint...@zvegintsev.alex · 8 months ago Author OpenJDK has only just finished the work to support XWayland, and so the timing of this bug is very unfortunate. It causes a CONFORMANCE test failure, which means that no JDK distribution, from any vendor can claim to support Java in this configuration (Gnome 46). This includes at least Ubuntu 24.04, Fedora 40, Manjaro 24. A fix for this needs to be in place and backported as a Gnome 46 patch for those distros.
