Fbdev exposes the video ram (or a shadow buffer of it) to all
applications. Only one can draw at the same time. It's a limitation of
the design. To fix this, your application has to stop drawing when you
switch consoles.

OK, thanks for info.
Quite a sad news, if you ask me.
Is there any ongoing work at solving that?

I don't think so. Both, SDL1 and fbdev, are pretty much dead these days.
The solution to fbdev is DRM, which does not have these problems.

You could your application under X11 to use SDL's X backend. X would do
all the VC handling then.

That of course works.
I was trying w/o X.
Do you think it is possible for
me to test other techniques of
drawing under kms console?
Or fbcon and X are all that we
have?
