Description Rafael Brandao 2013-03-27 16:09:19 PDT
On strange loop example, if you try to move around slides and there's a highlighted text (in this case it's a red text), then you can see a few glitches under the box that contains the text. One thing to note about it is that these texts have some effects when you put cursor on it. I can see this bug in a similar way on Qt and Nix, and more clearly on EFL.

Some investigation to figure out if this was a regression (tested on qt):
r147009 - displayed with artifacts
r143738 - displayed with artifacts
r138818 - not even displaying
r138735 - not even displaying
r138476 - displayed with artifacts

Looks like we've been like this forever, but at some point we've made it to stop working at all.
