I'm developing a game which is now in alpha testing stage and I'm trying to test it with all emulators, simulators, and devices I have access to.
The problem appeared with Tungsten W emulator. This is I believe the only OS4 handheld which supports the high density feature. The problem is that during animation images are often mangled after some period of play, they are a kind of "rotated", the sprites are shifted to the right, and pixels from the right border appear at the left border of the sprite. It's quite random, because sometimes bitmaps are drawn correctly, sometimes not. The sprites are drawn both with WinDrawBitmap() and WinCopyRectangle() from an offscreen window. And both get mangled. I would think this the the bug of Tungsten W or the Emulator, but it could also indicate some hidden problem in code which reveals itself only with this model. Has someone run into a similar problem? It seems that WinCopyRectangle() and WinDrawBitmap() I don't even imagine any approach to debug this. -- For information on using the PalmSource Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
