If "bpp" is 8, repeated SDL_SetVideoMode calling will cause Display error. about psplibraries

I have made a demo to demonstrate the error.
The following screenshot shows what the error looks like.

Here is the demo with source code. This demo displays a bmp with a palette for 5 seconds, then do the same thing again, and we could see the error. Then it switchs to bpp 16 mode, which works well.

Display error appears

Can you be more specific? e.g. what does SDL_GetError() return in this case?

One thing i see in the SDL port is, that we use an indexed shadow surface for 8 bit mode.
I guess there is some cleanup missing, when there are multiple calls to reset the mode.

It seems SDL_GetError() returns an empty string.
