On Wayland if You drag an image onto the GIMP window, specifically into the layers panel KDE just... stops. Not even the cursor moves. I don't know why it happens but its consistent on both my machines.
Just tested on a fresh installation in a VM, easily reproducible
Can't repro this on Plasma 6 dev Operating System: Fedora Linux 40 KDE Plasma Version: 6.1.80 KDE Frameworks Version: 6.4.0 Qt Version: 6.7.1 Kernel Version: 6.8.11-300.fc40.x86_64 (64-bit) Graphics Platform: Wayland Processors: 12 × AMD Ryzen 5 3600 6-Core Processor Memory: 15.5 GiB of RAM Graphics Processor: AMD Radeon RX 6600 Can you share more information of your system, like I have listed above?
Operating System: Arch Linux KDE Plasma Version: 6.0.5 KDE Frameworks Version: 6.3.0 Qt Version: 6.7.1 Kernel Version: 6.9.3-arch1-1 (64-bit) Graphics Platform: Wayland Processors: 24 × AMD Ryzen 9 7900X 12-Core Processor Memory: 30.5 GiB of RAM Graphics Processor: AMD Radeon RX 7900 XTX I also made a mirror bug report over on GIMP gitlab and someone was able to reproduce it. I was also able to reproduce it in a fresh VM https://gitlab.gnome.org/GNOME/gimp/-/issues/11446
Also can't reproduce in git master. There were come drag-and-drop fixed recently; let's assume one of them fixed it for Plasma 6.2. If you upgrade to Plasma 6.2 and still manage to reproduce the same issue, feel free to re-open this bug report.
