07-26 build on OS 10.2 1. Go to the noted URL. 2. Play QT movie. 3. Use vertical scrollbars to scroll down page. Expected results: QT movie continue to render properly when scrolling down page. Actual results: QT movie is distorted when scrolling down page. Workaround: Scrolling all the way back up to the top of the page eliminates the problem. Need to confirm this bug once 10.2 ships.

Using Chimera/20020724 on OS X 10.1.5, pressing Page Down then Page Up results in movie cruft left above the movie area.

doesn't distort for me. wfm

issue on 10.2, not 10.1.5

->sfraser from bug 160437: would bug 106691 or bug 106692 be related?

From notes in but 176649: QuickTime: scrolling with a quicktime plugin visible messes up. If you reboot your machine in Safe Boot mode (hold down the shift key), which disables video acceleration, and hence Quartz Extreme, this bug goes away, so I think it's something funky with QuickTime and OpenGL. What happens is that [NSView scrollRect:by] fails to scroll all the visible pixels; it's like parts are being clipped out (but not by QD clipping or visRgn issues, since I tested those). There's a commented out hack of calling [NSView display] after every scroll, but that slows things down.

This is apparently a known issue (it happens in Mail.app). I don't believe there is a workaround.

I don't know if it's the same bug. Build 2003010706 - 10.2.3 and QT 6.1. On iMac 400Mhz, QE disabled, graphic card don't have enough RAM. http://www.apple.com/finalcutexpress/theater/compositing.html Reduce the window to have the possibility to make a page down. Start to play the movie, make a page down by clicking below the thumb and then above the tumb in the scrollbar or by using PageDown-PageUp. A frame of the movie will remain on the previous position, covering the buttons under the movie. Must resize the page to refresh it.

This is the Panther countdown Quicktime movie on http://www.apple.com. I scrolled down and the movie becomes off-set and continues. It never re-aligns with the original thumbprint. In addition, though not shown in the movie, the countdown movie was still running on my Desktop after I minimized Mozilla to the Dock, though sporadically appearing every second or so. Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.5) Gecko/20031007 15" PowerBook G4 667MHz, OS X 10.2.8, Quicktime 6.4

(From bug 188620) Here's what Apple said about this bug: Some time ago you reported a problem with QuickTime and Real Video plugins (see below) in Chimera. I ended up filing a bug report on this (ID 3120292), and I've now gotten a diagnosis of the problem from our engineer. Here's what he said: "Using the -[NSView scrollRect:by:] method will not work with accelerated surfaces. The developer will need to move the actual view around the window by changing a containing view's bounds (.i.e. using NSClipView or NSScrollView). This way, when the view moves, it notifies QT and QT updates a 'surface' location which CG uses to determine where to render."

Josh, should this move to a core component? Presumably CocoaFox will have the same issue.

Mass un-setting milestone per 1.6 roadmap. Filter on RemoveRedonkulousBuglist to remove bugspam. Developers: if you have a patch in hand for one of these bugs, you may pull the bug back to 1.6 *at that point*.

dupe of bug 90814?

I don't see this anymore in 2.0b4pre, at least with Apple's new Trailers UI (http://www.apple.com/trailers/wb/wherethewildthingsare/ - I choose "medium iPod"), nor with this random "sample" QT movie: http://www.revolutiontwo.com/demo/tv/all-video/just-a-sample-quicktime-video.htm I don't see it in 1.6.8, either, though!? WFM? Actually, in 1.6.8 on my PowerBook G4, I see a little bit in the Apple Trailers UI, and none at all in the larger movie. Maybe we need someone on PPC to check this out in b3?

This bug has been buried in the graveyard and has not been updated in over 5 years. It is probably safe to assume that it will never be fixed, so resolving as WONTFIX. [Mass-change filter: graveyard-wontfix-2014-09-24]
