RenderTarget:clear() bug

Artiom

Hi!
I'm trying to use TNT Particles Engine with RenderTarget to create one fire and show it in different places. I need render to texture feature because if I create many particle emitters then it lags.
Problem is in RenderTarget:clear() function. It seems it works wrong. Let me show you an example:
This is original sprite where particles engine render it's emitter:

When I create texture from this sprite and use RenderTarget:clear(0xffffff, 0) function and then use this texture and create bitmap I get this:

That looks weird, because I use alpha 0 and get totally opaque bitmap.
If I use blue color I get this:

Finally if I use black color (RenderTarget.clear(0x000000, 0) I get this:

Similar to original but not the same.
Please confirm. Similar post was here: http://giderosmobile.com/forum/discussion/4392/rendertargetclearcolor-alpha#Item_8

@Artiom yes there was previously submitted a render texture bug, maybe this is related, let me check
either way adding it to our internal tracking, for Atilim to look, when he gets back

@ar2rsawseen,
Any updates?

@ar2rsawseen,
@atilim,
Seems just transparent pixels are black for a some reason..
Maybe make a feature {transparentColor = 0x000000} for a RenderTarget?

I know that @atilim finally got to this bug in the buglist backlog and is checking it right now, but I don't know if it was fixed yet

Currently, I'm working on it. I'll post an update when I catch the origin of the bug.

Don't forget the memory allocation bug with render target.new using various amounts of ram depending on the scale mode (it crashed in some cases on a Samsung Galaxy Fame).
