Ext Designer Preview vs Real app rendering differences

[aorlic]

Hello!

I've noticed slight differences in Ext Designer's preview and the real app's layout.
For example, take a look at the attached example. There is a slight difference in rendering of the UserData FieldSet contents between these two views...
Some hints, ideas or good practices in order to avoid these unpleasent situations?
Thank you,

Aleksandar.

We try to be as pixel perfect as possible in Ext JS and Sencha Touch but there may be some slight differences in between browser to browser.

The Ext Designer preview is a webkit browser and you would probably find it more similar to the results you would see in Chrome or Safari.
