RC6 is 8.4.9 for Mac OS X, and 8.4.11 for Windows. (FYI: Pd-extended on GNU/Linux, Tcl/Tk is not included, so its whatever you have installed)

There have been some other little bugs like that, but I don't know what the source of them is. I guess I too have just gotten used to them.

Hey Hans,

I did not check what version of tk your using in your RC6 (where the "ugly" screenshots came from) Looks like on linux I'm using 8.4.9...

I think think its some tk bug, but damn a few stray pixels are an anoyance, at least for small vector b&w stuff like PD.

Hi Hans,

#1 It looks like my antialiasing settings for the past couple years has simply aliased away my perception of this problem. In fact it has probably been around for longer than that

#2 I think your view of "normal" is not what has been normal for PD (ie not on OSX) check out the following attachments, zoom in real close and take a look. Both are the exact same patch, rendered by OSX and linux.

There is certainly something wonky happening with the tk drawing, some elements are one (yes one) pixel off. I did notice when making connections that even the start of the connection does not start at the outlet, but floating one pixel above it. :(

Summary of weirdness:

* The "rectangle" used to draw a PD inlet is exactly one pixel taller than the outlet. (huh??) on OSX this means we see the whole in the recangle, exposing that it is a non-filled rectangle

* The line that connects the bottom right corner of a message box to the inset part seems to extend exactly one pixel past the inset part, giving us a single pixel artifact

* the circle in a bang is really wonky, looks slightly mashed into the lower-left corner and is totally asymetrical, where on linux the curcle is centered and symetrical.

Yes these are very tight issues (on pixel here and there) but they are distracting me and actually make the PD (clean) interface rather junky. (at least at a low-enough resolution we can see them).

James, could this be an artifact of the new tk drawing instructions? Some things are strange, like the inetets of the IEM guis don't seem to have this same issue as the "original" PD objects.

I just don't understand how the stable version of tk is doing this, I guess we're the only ones left using the "canvas". *sigh*

And yes Hans I agree that the connections really look nice with the AA, and I understand your position. I think it was rather the shock of that the AA was hiding from me that made me so unhappy with having the AA turned off...

so much for consistancy.

The inlets and outlets look normal to me:

It would be nice to have the connections anti-aliases, as long as it can be done separately from the boxes. Anti-aliasing on the boxes just makes everything look out of focus.

Hi again hans,

trying to use RC6 rather than pixelTANGO on the g5 here at work. (I guess you include a g4 Gem binary in there?)

Anyhow why are inlets drawn twice as big as outlets? I could really deal with the lack of antialiasing on the patch-cords, but the inlets are really ugly.

I don't see this on any other platforms, and my pixelTANGO installer does not do it... ?
