I see... Hm. The point is that most of us is not really deep into the WX
code base, and GNU Radio is planning to move away from WX to QT, and
since I can't reproduce the problem locally, it's going to be very hard
to get you running. It really *is* an odd failure if only the scope is
failing.
I have one more idea: might be something with OpenGL acceleration; WX
always was a bit flakey on that side, but hardware accell for drawing
lines is really helpful... But maybe on modern machines with CPU cycles
to spare, maybe creating  ~/.gnuradio/config.conf with the lines:

[wxgui]
style = nongl

does the trick (hell, if I knew where .gnuradio is on a windows
machine...).

Generally, if your application is "simple enough" to just switch
Generate Options from "WX" to "Qt" and replace a few GUI elements, then
I'd recommend using Qt; it's more modern, and it will stick around
longer. Most features can be configured even at runtime using
"middle-click" on the visualization.

Greetings,
Marcus
