SUMMARY With discs in multiple optical drives, the GUI prevents interacting with any other drives after starting the first one. STEPS TO REPRODUCE 0. Requires a minimum of 2 cd trays with media inserted 1. Click "Start Ripping" on an audio disc...start 2. General GUI becomes inaccessible while the rip is in progress. ACTUAL RESULT I cannot use the GUI to start a rip on any other, idle tray with media inserted and recognized. EXPECTED RESULT I expect the GUI to be able to background the rip process window, so I can interface with another unused drive/cd, and begin a simultaneous rip of a different disk to a different directory location. SOFTWARE/OS VERSIONS Linux/KDE Plasma: (available in About System) KDE Plasma Version: 5.25.3 KDE Frameworks Version: 5.96.0 Qt Version: 5.15.5 ADDITIONAL INFORMATION I have the k3b process wrapped in firejail, and I've already gone through the hoops to make everything work as expected from a usability perspective (i.e: k3b can burn/rip cds individually, and obtain cddb info). I don't imagine the sandbox is causing the issue with window management, this seems entirely within UI/UX of k3b itself.
