Alrighty...doing that now...hm, I didn't try it with VM yet, but I see no change in the behavior of my revamped simple testcase that mimics it...trying VM now...yup, no change in the behavior (i.e. spaces between the strips are still present in both VM and 'example-2' in my revamped testcase that I included in my earlier email). But then, as I said earlier, I'm still not sure that this new behavior is actually an XEmacs redisplay bug. I mean, what if you had an extent that had a small begin glyph but a lot of text in the extent and this text went past the end of the screen, you'd expect that to wrap, correct? Assuming truncate-lines was set appropriately of course. I see no difference here - the text in the extent is going beyond the end of the screen so it *should* wrap, no? Thanks, Chuck -- Charles K.

I hope you didn't misinterpret my meaning there: I was talking about the text wrapping only, not the glyph (i.e. glyph goes offscreen but the text that would be drawn offscreen wraps). I don't think that the glyph should wrap (that'd look pretty wierd for most images I think, especially in VM where it's doing large images in strips) but I'd expect the text to do so (as it now does).

Right, and that seems to be what your first patch fixed to be "correct" (as I said I saw no behavioral change with that last patch you sent so that had the same "correct" behavior). So Kyle, do you have a special reason for including that space in the extent? If not, would you mind removing it from the extent for the next version of VM? Thanks, Chuck -- Charles K.

I thought the testcase I had did that very thing in both the 1st and 3rd windows, and I didn't remember seeing any visual difference...huh... Thanks for all your effort on this! Chuck -- Charles K.

And I believe that it looked correct before your last patch as well, although I cannot be certain without reverting the patch, which I can't do right now. And in fact not inserting the space into the extent made the glyphs display ok before you patched redisplay at all! At least with the space before the extent, I don't think I tried it after the extent since that'd be after the newline in the extent anyways... Chuck -- Charles K.

No space or a space before the extent with the glyph displayed just fine pre-patched (except for the backwards refresh stuff). That's why my testcase popped up 3 windows, one with just the newline, one with space & newline in extent, one with space before the extent, and only the middle one displayed badly.

That would explain why applying that last patch didn't seem to affect what I was seeing as well as some of the conflicting paragraphs we had over the last couple of emails. :) Thanks, Chuck -- Charles K.
