All WebKit views turn grey when scrolled after connecting second monitor Yes, this is strange, but it's reproducible for me, every time. New in Leopard IIRC. To reproduce: 1. Launch a WebKit using application (Safari, iChat, Mail) 2. Sleep your MacBook Pro and disconnect your 30" monitor. 3. Open up your machine, use it for a while. 4. Sleep your machine, reconnect your 30" monitor. 5. Scroll any webview, and watch it turn grey as it scrolls (it repaints the same section several times until it turns grey it seems.) The initial paint of the webview is fine. Repaints cause it to turn grey. Resize the webview to get all your colors back.

Interesting: Colloquy does not seem affected. However I'm certain I've seen this problem with iChat, and I'm pretty sure I saw it in Mail.app as well.

I have had this same thing happen. I recorded a video of it in action http://www.youtube.com/watch?v=J9ytvPhV9ew&fmt=22

I think I've been hitting this bug since I got my 30" in 2006. So it's not new. If I'm remembering correctly, I've seen it affect other WebKit apps, like iChat and Colloquy too. Although I don't remember seeing it in Colloquy in a long time. I haven't used iChat since about 2007. I can reproduce this regularly in Safari.

(In reply to comment #4) > I think I've been hitting this bug since I got my 30" in 2006. I hadn't realized how old this bug was. My issue is probably something different. I'll search bit more.

Nah. You're definitely hitting the same bug. Or at least it looks the same to me.

Actually, I just saw this bug with TextMate's scroll area. So unless TextMate is using WebKit for display, this bug is not isolated to WebKit and likely needs to move to Radar.
