Hello Roger and All,

This is strange ...
I won't repeat nor leave my comment each by each, only one item.

Very strange here!
As you remember a while back, I came to know that you didn't have any
Console Switching problem and you realized this problem exists.
I thought the problem was not caused by svgalib 1.4.3 nor by Linrad
but caused by my video card Matrox Millennium G400.
In addition, simply replacing the card to NVIDIA GeFource2 fixed the
As you didn't have this problem on your ATI Radeon too, I've decided to
forget G400 and buy other brand someday.
On the contrary this time you DO have the problem and I DON'T with
the same svgalib-1.9.17.

Well, above relates to Console Switching problem though during this write
I've found some other things which looks similar to your problem;

Linrad started from console (not from Xwindow):
After exiting Linrad the screen is corrupted completely.
However after simple switching to other console and return to the corrupted
console there is no more bad screen, just a normal one.

Linrad started from Xwindow (FVWM, KED, Gnome):
No problem what's so ever.
