.6] Upside down checkmarks

This needs to be investigated early in case we need Apple to fix a bug.

This doesn't happen in Firefox 3.0.3, and I've found a regression range: firefox-10-13-02-mozilla-central firefox-10-14-02-mozilla-central http://hg.mozilla.org/mozilla-central/pushloghtml?startdate=2008-10-13+00%3A00%3A00&enddate=2008-10-14+05%3A31%3A00 Markus' patch for bug 394892 is in this range, so I think it's very likely to have triggered this bug ... which (on the face of it) seems likely to be an Apple bug. Markus, do you have access to a copy of SnowLeopard? It's now available on ADC (to those with at least a Select membership). It should also be possible to get a copy from Josh. In any case I'll keep digging, since (I think) it shouldn't be too hard to find the trigger.
Argh. I think this happens because Apple fixed a bug... IIRC we explicitly set up a flip transform because otherwise checkboxes would be upside down on 10.5. I don't have a copy of 10.6 yet.
Here's a patch that seems to fix this problem. That it works seems to confirm what Markus says in comment #4 -- Apple appears to have fixed a bug in SnowLeopard that we previously had to work around (in Leopard). But there are *lots* of other places where we use (vertical) flip transforms in nsNativeThemeCocoa.mm, and where they still seem to be needed. Though it's a bit hard to tell -- buttons and scrollbars and the like are (aside from the text) usually vertically symmetrical. Markus: Are the other places we use flip transforms in nsNativeThemeCocoa.mm also (in effect) workarounds for Apple bugs? If so, should we try to get one or more of them fixed in SnowLeopard? That is, is it worth our while to isolate them and report them to Apple as bugs? The fewer distinct bugs there are (and the fewer bug reports we'd have to open with Apple), the more "economical" it would be to report them to (and, presumably, the more likely Apple'd be willing to fix them).
Here's a tryserver build made with my patch from comment #5: https://build.mozilla.org/tryserver-builds/2008-11-12_13:email@example.comfirstname.lastname@example.org Marcia, please bang away on it and let us know what you think.
Steven, before I review your patch, I'll write a small testing app that tests all kinds of ways of NSCell drawing. We really need to know what triggers drawing problems on which OS versions, especially since I'll change a lot of the drawing stuff in bug 450800.
Sounds good to me, Markus.
The build in Comment 6 resolves the issues I was seeing both in Import and Preferences with the upside down checkmarks. The world has now been righted...
My patch in bug 450800 also fixes this bug.
Comment on attachment 347842 [details] [diff] [review] Possible fix (In reply to comment #10) On the strength of this comment, and of the continuing work in bug 450800 and bug 465069, I'm marking my patch obsolete.
Should be fixed by bug 450800.

Marcia, could you please check if everything is ok on Snow Leopard? Thanks.
I can check, but will do so when I get a new seed which hopefully should be soon.
