#7 Colour tinting makes transparency fail on single characters
Occasionally, some characters in a window set to fake
transparency will not have transparent background. So
far, I've only observed this with irssi; a screenshot
of the problem is attached. Might this be a problem
that occurs when redrawing lots of text at once (as
irssi changes all text in a window occasionally, eg.
when switching windows)?

Send me the link for the program (or the program itself if
it's not too big).
You can mail me directly.

I have just noticed that for some reason, the problem only
occurs if the window has colour tinting set; either via fake
transparency and the <tint> directive, or by alpha
transparency and <color>. I've used Console without tinting
and alpha transparency for quite a time now without the
problem ever coming up again; then set a window to use alpha
transparency plus <color> - and within a minute, the problem
reappeared.
I commented the <color> directive out to verify, and the
issue is gone.

Hm... This is very strange... I see no reason for fake
transparency failing with tinted background, since the
background is tinted during initialization, so the
background painting is done with the tinted image... But,
I'll take a look. Thanks for the effort :)

Ok... I've just tried running irssi (with latest cygwin
update) with the Console 1.42 and 1.5 beta. Both have tinted
fake transparency (I run 1.42 with the default console.xml)
I haven't seen the painting problem.
The fake transparency problem did occur to me on GnuWin32
less as well (repeatable, every time) However, it happened
only with a Release build of Console... Debug build didn't
have that problem.
I've tried irssi and less again, and I've seen no problem
(on my W2k box). It could be graphics card problem or
something. I have updated the drivers for my Radeons - 7500
and 8500 on both my machines (WinXP and W2k) since the last
reports. I'll try this today on the WinXP box...

Try the latest v1.5 beta. I've changed background color
painting a bit...
