[Layer view looks 'fuzzy' in 15.02]

Hi pm_dude! Tried with 15.04.2 and the problem was gone. Yes, it used to happen with every model, and it happened with 15.02 and another earlier version that I don't remember. But now it's gone . Thanks!

[Layer view looks 'fuzzy' in 15.02]

Hi! I'm having trouble with the layer view in Cura 15.02. Lines in layer view look like this in 15.02 for me:

Switching back to 14.07, it looks like this:

As you can see, they look sharper in the last one, and it's possible to distinguish every line from each other. It's not a thing that keeps me from using 15.02, but has anyone had the same problem?

Sorry if my english isn't very good, native spanish speaker here

Thanks in advance!
