There is a known issue with some regional formats that causes bad loading and rendering of board and chip views. When the problem occurs, you may see some shapes appear with missing content and exaggerated size. The problem is particular to formats that use a comma (',') or any character besides '.' as the decimal separator.
We will be working on a solution, but in the meantime there is a workaround.
To use the workaround, you need to temporarily change the format settings in Windows to a format that uses '.' as the decimal separator such as English (United States). For example, in Windows 7, you can access the setting through Control Panel → Change display language, click the Formats tab, and select “English (United States)” in the “Format” drop-down.
