Which Lazarus? I've never seen text jammed to the right. And the buttons look perfectly reasonable. In the attachment there's a screen shot of TFloatSpinEdit, TSpinEdit and TUpDown taken from Win10 (I don't have a Win7 at the moment, but I did not remember any essential difference). Lazarus version is 1.6.4, same results with trunk and 1.8RC.
Are your programs themed? I.e., under Win XP, do they look like Win 95? Drawing of controls is often split in a themed and a non-themed part, and I could imagine that both parts may be different regarding pixel offset etc.
