Icons & widgets spontaneously appear on screen or are rearranged on Galaxy S III after root

[Stan Ryndin]

After rooting T-Mobile Galaxy S III & installing Darth Stalker S3 Edition Version #7 custom ROM (4.1.1), I sometimes have icons & widgets spontaneously appearing on my screen ("desktop") (and I don't mean after I install an app) or rearranging. Sometimes it happens after reboot, sometimes without a reboot. Is this an issue with this specific ROM? Any ideas on how to fix this?

Thank you in advance.
