"DrawPrimitiveUP(): UNKNOWN" in either RenderCopy or RenderCopyEx

SDL Development

SYMPTOM:
after a few game cycles I am getting “DrawPrimitiveUP(): UNKNOWN” error on
response to the call to either function: RenderCopy or RenderCopyEx.

USAGE:
im using high pace SDL_CreateTextureFromSurface for creation from a fixed
surface array and SDL_DestroyTexture for cleanup - yes, each object has
his own texture, for different alphas etc.

IDEAS: ?

Try turning on the debug DirectX runtime? It may print more informative
messages.
Also try explicitly initializing the OpenGL renderer and see if you get
different results?

WORKAROUND (while i cant figure out why this happens but i read somwhere we
need to explicitly clear OpenGL texture buffers)

  1. Cut original texture from originally 512x32 to 16 individual textures of
