<p>Hi all,</p>
<p>I've noticed that the black box problem can come from the FXAA
enabled in the render settings (I have the same problem with my
computer & 5.4) but it does not explain the problem with
opacity. (my graphics card is a GeForce GTX770M)<br>

bug in 5.4.0 with some graphics hardware that we are trying
to fix in 5.4.1. Can you let us know what your gpu is? Also
try 5.3 and let us know if both problems work there.<o:p></o:p></p>

opened the first Example Visualization and selected
Clip2 under can.ex2. When I tried to adjust the
Opacity under Styling in the Properties tab, any
