--- Comment #5 from Ken Taylor <taylor...@embarqmail.com> --- First test result Installed Ubuntu Mate 18.04 on the old Dell machine Installed all available updates and rebooted to load latest kernel Installed K3b from the Ubuntu repository K3b version 17.12.3 and a bunch of dependencies installed (I can provide a list if that would be helpful) Launched K3b top shows minimal CPU usage by K3b Clicked on "More actions" (long button towards the bottom of the screen) and selected "New Video DVD Project" top still shows only 0.3% CPU for K3b At this point I clicked on Project on the menu and Clear Project. I confirmed my desire in the dialog which appeared. The program is now unresponsive to any mouse actions. top shows K3b using 99 - 103% CPU Gnome system monitor shows K3b totaling utilizing 1 of 8 virtual CPUs Clicking on the window Close X eventually brings up the "K3b not responding" dialog. I select Force Quit and the K3b window closes. top still shows K3b consuming 100% CPU Gnome System Monitor still shows one virtual CPU pegged at 100% I can end the K3b process and system utilization returns to normal That is about all I can say about K3b on Ubuntu Mate. I have the Kubuntu image and will install it now. Ken -- You are receiving this mail because: You are watching all bug changes.
