I am not sure about the reason of the problem but can it be that some "[" or "]" are present in the name of the applications/icons on the desktop?
I've observed a similar problem having an app name containing these two characters.
Ultimately you may have a look into ~/Desktop/.directory
hi, i'm getting the same, all my icons appear to be messed up, i've tryed to change this setting:
Control Center -> Appearance & Themes -> Background -> Advanced Options -> Width for icon text (set to 90, was auto or something...)
without any luck, after this i've rebooted the system and all it seems to be OK, but now, after one day after that the icons are all messed up again, this is really anoying
