apps crashing and main menu icons disappearing

[abhishek dubey3]

Apps like chrome and music streaming apps like saavan crashing on nexus 5 lollipop upgrade. Front screen icons including main menu are disappearing. Though clicking on the same positions where the icon existed is opening the apps. But only icons are disappearing. I am having screenshots as well. Is the issue known for icon disappearing from front screen in lollipop. Please help me if you know the solution.
