nemo: Set folders to open each in their own window. Open a folder that has several sub-folders. Lasso two or more sub-folders in that window. Right-click and choose Open. Nemo crashes!
nemo: could not install nemo-dropbox. downloads, displays “100%”, hangs. I was able to install dropbox from dropbox.com
muffin: delete file on desktop, confirmation dialog doesn't show in middle of the primary screen, but in middle of the workspace (i.e. if you have two screens, it shows on the right hand side of the left screen)
cinnamon: sometimes icons change from default Mint icons to some other (maybe some fallback icons?)
Clock says 15:38. Go to time settings. Turn off network time. Turn it back on. Wait for 10 seconds or so.. time updates to correct time and says 16:38. (either Cinnamon loses track of ntp when disconnected/reconnected to network, or it fails to use it at login time)
"Send by email" is showing when right clicking Computer, Home, Trash or removable drives icons on Desktop (also another really minor issue is that “Send by email” and “Format” should have “…” on the end)
cinnamon menu doesn't listen to menu changes outside /usr/share/applications? install shotwell for instance (uses /usr/share/menu)
mint-x (metacity): 1 px frame around windows prevents the rightmost pixel of the right scroll bar from being clickable. Open nemo full screen, with Adwaita you can throw your mouse to the right edge of the screen and start scrolling, with mint-x you need to move 1px left
