Finder cuts off thumbnails/icons
Incase you get this same glitch that happened to me.
problem
Using finder in hidden sidebar mode.
After arranging thumbnails by name - they shift left and half of them are hidden by the left edge of the finder window.
Resizing the window doesn't help, neither does arranging them again or changing view. (the list view gets cut off too).
solution
Use the menu 'view > hide sidebar/ show sidebar' in order to snap it back into place.
