DRAWRECT stutters when in animation, don´t know if this is new as I never tried that command on a Caanoo till now.

About the rest, I have more or less this to display stuff on my code
Code: (glbasic) [Select]
CREATESCREEN 1,200,428,240 ;// Virtual Screen

// --- STANDARD SETS
IF comp=0 THEN SETSCREEN 320,240,0 ;// Caanoo
IF comp=0 THEN DRAWSPRITE 200,-54,0                         ;// Caanoo

What I get on screen is the game without those -54 on the drawsprite, they are like 0.
I appended a crap pic.

Of course all works fine as expected on the PC

Oh no. Can you zip a tiny test program for this bug?

Ok, will create a little test...I just found out that DRAWRECT is not a culprid here on the stutter but ZOOMSPRITE...
Will post it later today.

Here the test project, I´m not sure anymore just what is guilty on this behavior and I found a couple more strange things to boot.
Appended is the usual crappy picture and the zipped project.

As with the picture, you can see that the final drawsprite of the virtual screen is not drawing it on the correct place -54 but on the 0 (ye the thing should display centered).
In app, you cycle between modes with space bar on PC and A button on Caanoo.
Here the more strange results I get on the caanoo:

MOVE SPRITE - things flicker a bit but, when the sprite is moving below 0x0 coords, things stutter a lot, specially on the lines of the lower right part.
ROTO SPRITE - very slow but the whites in sprite either become alpha or the same color of the drawrect used to paint the background of the
                      virtual screen.
ZOOM MASK - The mask stutters when the scaling is above 1x, most noticeable on the left corner.

Apart from these visual things, everything else in my original game is working fine.
I thought that these issues were related to the virtual screen on the Caanoo, but removing it from code, the performance and issues were the very same.
Finally, everything works fine on PC.

EDIT: adding the code.
EDIT2: all .bmp are 24 bit rgb888. The mask is done with the pink color.

Its because the sprite is bigger than the screen. I have to check...

Hopefully that also deals with the positioning of the virtual screen, maybe both problems are related. Let me know if there is anything I can do to help.
