Hi,

I reworked the code a little bit and now I got the gol stuff working on MorphOs too (not using the VBO stuff
anymore).
But now I am facon the next problem: all images which are using alpha channel (like the character) are
not visible anymore. On Linux, Windows, AOS4 everything is fine.
Sadly I did not had the time to have a deeper look into it.
Here is a screenshot of the problem:

hi,

You use alpha with OpenGL renderer... no chance... it's a big bug of SDL2 now....

in SDL2 readme :

KNOW BUGS:
*************

- SDL_CreateRenderer with SDL_RENDERER_ACCELERATED is broken if you use SDL_BLENDMODE or
tranparency color with OpenGL renderer, you need to use SDL_RENDERER_SOFTWARE.
Dont ask me to fix that, i dont have any information on it, maybe fix on next release of MorphOS (3.16)..)

Yes, this should not be a bug in SDL2, because it's working fine on other platforms.

EDIT: So no OGL support on mos for now, but neverstheless, it's mostly done:

I update some of my ports and work on new port (Thanks to MorphOS 3.16)... so wait and survey MorphOS-storage

Have fun !
And thanks top MorphOS team.

I'm glad to see that the SDL2 is now used more than by myself (Doom3/SM64, deviluationx... to name the biggest ones)

Now in next release of SDL2, I implemented some missing features:

- SDL_WINDOW_FULLSCREEN_DESKTOP
- SDL_RENDERER_PRESENTVSYNC (note: vsync is always present in real fullscreen mode)

just one exemple with SDL_WINDOW_FULLSCREEN_DESKTOP and opacity window (to test i just edit my bePlayer): https://ibb.co/7CL1S3W
