Tearing in clear textures.

[nihohit]

When I run an animation that involves a partly clear (invisible) texture on a slow computer, there's "static" tearing which disrupts the view. This happens regardless of Vsync or whether there's a framerate limit set. Is there a known cause for this?

Are you drawing a part of the same texture on it?

[nihohit]

No, In the animation I keep removing the first frame and then draw the next one.

It's hard to help you without seeing your code.

Would you be able to write a complete and minimal code that reproduces this problem?

I'll try, the next time I'd be near that computer, but it's not a code problem - on my home desktop there's no tearing.
