STEPS TO REPRODUCE 1. connect a usb flash drive to usb port 2. copy a big file (I have used a 867 MiB video file in my test) to your flash drive 3. wait for 'Copying (Finished)' notification from Plasma 4. try to suspend your system to RAM OBSERVED RESULT nothing happens and the user receives no feedback EXPECTED RESULT feedback like a notification telling us that suspend to RAM is not possible due to data transfer in progress or similar SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 5.24.90 KDE Frameworks Version: 5.94.0 Qt Version: 5.15.4 Graphics Platform: Wayland ADDITIONAL INFORMATION This is another consequence of the annoying bug 281270
another thing: after the provided steps, Plasma suspends the system to RAM when the file transfer in background is completed.
