Hi Telerik,
We have just updated to Q3 2012 release. After that, some bugs appeared in Metro style. Corners for input controls have been squared before updating the release. After update are rounded (see attached file rounded.png).
When mouse cursor is over the control, corner is changed to square (see attached file squared.png). The same problem appears in the filter controls in grids (see attached file grid-filter.png).
Regards,
SCT
