I have a problem: some of my custom shortcuts stop working after rebooting. All of them are <Primary><Super>KP_number and <Primary><Super>number and I use them for moving windows between workspaces. They all remain in the settings and I can make them work again by removing them and adding again. Other shortcuts still work and my <Primary><Super>KP_1, KP_2 and KP_9 didn't get disabled. Last time only KP_8 worked afair. I set shortcuts using Settings Editor, Workspaces and by directly editing some of xmls. If any other information is needed I'll provide it.
I'm using the newest Mint "Sophie".
Thank you in advance
