Error reading pixels from hardware bitmap!

I do not understand this error message. It happens when trying to mode switch by hotkey.
The GL Galore guide tells me that:

"Please note that it's not necessary to handle mode switches manually in case
you're not using the OpenGL API directly. Hardware brushes allocated by GL
Galore will be automatically transferred to the new GL context by GL Galore
so you don't have to do anything about them. It is only necessary when
programming OpenGL directly."

It can be seen in the Smoothscroll.hws example script too.

Yes, this is a known issue but it only happens on MiniGL. So far I haven't found a way to fix it but it is known.

This has now been identified as a MiniGL bug. See here.

@Andreas

Is this also a bug in TinyGL?

I'm getting this error with BeastScroll and GPUScale from RebelSDL examples. I'm using MOS3.17

Not a bug but rather a limitation. TinyGL doesn't implement everything of the OpenGL standard.
