SUMMARY Drag targets like the Show Desktop widget on a panel, or the desktop view itself, react very slowly to large files (a 22mb image in my case) dragged over from Firefox (not sure about other browsers), whilst the same doesn't happens with large local files or small web images. STEPS TO REPRODUCE 1. Go to a 4k wallpapers site 2. Find a full size preview of a large one 3. Attempt to drag it into the desktop or through a widget OBSERVED RESULT Slow reaction with the no-move cursor EXPECTED RESULT Slowliness should at least begin to take effect when I drop the file, file data is irrelevant to most widgets until I take action on it. SOFTWARE/OS VERSIONS Arch Linux, Kernel 6.14.9 KDE Plasma Version: 6.3.5 KDE Frameworks Version: 6.14.0 Qt Version: 6.9.0 ADDITIONAL INFORMATION DDR3 RAM 3.2GHz 8 thread processor
Cannot reproduce on current git master with a system with the following hardware characteristics: Processors: 16 × AMD Ryzen 7 7840U w/ Radeon™ 780M Graphics Memory: 16 GiB of RAM (14.9 GiB usable) Graphics Processor: AMD Radeon 780M
I can reproduce on current git master - the size of the image doesn't seem to matter in my case, but it does cause very rapid drag-and-drop motions from either Firefox or Vivaldi to the Plasma desktop to not work. Thanks!

I'm definitely on the lower end side* and the time it takes for the system to react to dragged files seems noticeably proportional to file size, even the little thumbnail that appears when an item is dragged takes time to load, from memory to memory that is. The whole plasmashell seems to briefly freeze on large dragged files but it's not a serious problem. *: the lower end in question: CPU: AMD A8-5500B RAM: 8GB DDR3 (7 usable) GPU: (integrated) AMD Radeon HD 7560D
