Title: Ubuntu 24.04, mutter: drag and drop does not work between x11 and wayland applications Status in Mutter: Fix Released Status in mutter package in Ubuntu: Fix Released Status in mutter source package in Noble: Triaged Status in mutter source package in Oracular: Fix Released Status in mutter source package in Plucky: Fix Released Status in mutter package in Fedora: Won't Fix Bug description: Original report[1]: ---------- Description of problem: Unable to perform Drag and Drop using XDND protocol from Xlib application to application running on Wayland display server natively. How reproducible: always Steps to Reproduce: 1. compile attached file with "gcc XDnDSource.c -o XDnDSource -lX11 && ./XDnDSource". Attached file is a simple drag source client, written using XDND protocol. It has single mime-type to transfer: `text-plain`. 2. try to perform drag and drop starting from black area. 3. drop to gedit, firefox, etc. 4. <fail> Actual results: It fails to find any window having XdndAware property(except for apps running on XWayland), so it unable to perform drop action. Expected results: Performed drop. Additional information: The same example works for Ubuntu 21.04, Oracle Linux 8u5 on Wayland, but not on Fedora 35. ---------- The issue was fixed in Gnome 47 (plucky, oracular), but still present in Gnome 46 (noble). Attached reproducer from the original report. Why it is important: --- 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.
