Errors in syslog

[eduncan911]

Just a drive-by dump of some errors I'm noticing in syslog/journald

Version: v16 OS: Pop_OS 19.04 (aka a "skinned/extension-ed" Ubuntu 19.04)

What was I doing? Changing transparency with shortcut SUPER+9, which unfortunately also launches an app in my Dash-to-Dock extension (trying to fix that).

I had the same issue. Please see the workaround here.

Eventually, I decide to change the default shortcuts.
