After updating to 1.7 corner radius was now limited up to 50px only. Sure, you can still manually edit grab the corner beyond the 50px limit but the Pixel radius indicator on the bottom will be stuck in 50px, so there will be no way to tell how many pixel your radius made after hitting beyond 50px.
Before i can manually type the corner radius and it does not matter if it's beyond 50px. now if you put 100px, it won't recognized it.
Before you can do this image from bellow, but now you can only manually input up to 50px, beyond 50, it wont recognize the number.
