Hi, on Picasso96 screens I get regularly some trash on the screen. Sometimes some pixels are drawn which seems to be part of the Picasso video memory (if I move the window containing the trash pixels the pixels are moved as well but if the window is refreshed the pixels are gone). If I move a window typically one invalid line on the screen is not refreshed. If I move the mouse then the line is also refreshed. This may be a bug in the picasso glue code (picasso.c) or the sdl gfx driver. AGA screens are not affected by those problems. Are those known problems? Regards, Jochen
