wxgui scope sink - multi channels can have random alignment
|Assignee:||Johnathan Corgan||% Done:|
When the scope sink is used with multiple channel input,
even if each channel comes from the same source,
the display will have an often random offset among channels.
The random offset seems to have a "random" chance of happening after flow graph initialization.
This probably depends on system load and when the graphics become marked "on-screen".
Locking/unlocking the flowgraph may exacerbate the issue.
This is believed to the the creative enabling/disabling of the gr.copy block.
Perhaps a multi-IN/multi-OUT copy block is in order. Or not using it.
