Summary: Screen not/wrongly updated while doing reverse_frame

Initial Comment:
I start up openMSX
- set renderer SDL
- set scale_factor 2
- set scanline 0
- set blur 0
- set glow 0

I reverse to where the MSX logo is showing up and press pause.
I type: reverse_frame
Now the logo disappears and the whole MSX screen becomes blue (background color).

Even worse: I press F10 to remove the console. Console is still showing, but in lower brightness...

Unpausing makes drawing work again.

When doing advance_frame after reverse_frame, I first get a black screen. Doing another advance_frame I see the screen drawn again. More advance_frame commands after this work as expected.

When I wait until the full MSX logo is drawn and then do reverse_frame, the screen doesn't become blue, but still shows the MSX logo. It keeps showing it, no matter how often I do reverse_frame from that situation... Very weird.

For TASers, a working advance/reverse_frame function is essential.

On SDLGL-PP I get only black screens when doing reverse_frame and there the console does disappear when pressing F10.

I get the same behaviour on openMSX 0.9.1.

It only seems to happen when a GFX9000 is inserted...
