Re: [wxVTK] Double buffering

[Pierre F. <pie...@gm...>]

Not that I know. I ran into this bug a few months ago by testing softwares
on recent nvidia graphic cards, where I experienced lots of flickering. It
turns out that by explicitly setting double buffering to On solved the
problem. As I am not an openGL expert, I was pretty OK with this workaround.


There are some discussions about this issue that you may find useful:

The trick of activating the double buffering works well on any system I
tried (windows, linux - various distributions - and macosx). Sorry for not
reporting it to the list but things went a bit crazy around here these days
(and months).

Hope this helps,
Pierre.
