home page UI issue

i am admin of my suitecrm, my home page is visible perfectly there is no issue… but i have created some users and found that when i login through there credentials there account whole content (i.e. home page, lead page etc.) all are viewing in zoomed in condition even when i have set zoom for browser to default state. but on the same browser my (admin) account is running fine it is perfectly viewing.
the first image attached to it is a user account at default zooming state in which all labels are not at proper place. see the arrow
the second image is of the same account at 75% zoom, here all tabs are correctly placed.

Please help me out why it is happening… except admin account all other user accounts are not display in proper way
