Hi list, We've been trying to track down a bug in our CALayer-based view in which the red dotted underlines for misspellings appear in the wrong place. It looks like they're being drawn in an unflipped graphics context, even though we're drawing the text into a CABitmapContext we've created ourselves.
While working on an unrelated bug, I created a simple NIB file that contained a layer-backed NSTextView inside a layer-backed NSScrollView that's set to automatically resize with its window. Simulating the interface (Cmd-R in Interface Builder) showed that even this is broken. The red underlines repeat themselves horizontally across the view and leave artifacts around when the text is deleted. Furthermore, if you drag the window resize handle up to shrink the window, the text stays put but the red underlines start sliding about, fixing themselves when you let go of the resize handle. It looks like NSLayoutManager and CALayer just don't mix. I've filed a radar at rdar://problem/8644121. I'm also curious if this is related to rdar://problem/8009542 (Scroll view misbehaves with flipped layer-hosting document view), since text views are flipped. I've put a demo project up at http://dl.dropbox.com/u/9699077/CARedSpellingUnderline.zip and a screenshot at http://dl.dropbox.com/u/9699077/CARedSpellingUnderline.png . Has anyone else seen anything similar to this and/or has ideas for a workaround?
