10.4: A programmatic fix for an Exposé slowdown
My frame rate went up to 60, but does anyones window break up around the edges when they move them around?
10.4: A programmatic fix for an Exposé slowdown
Yes, this happens to me as well. There seems to be a horizontal redraw guide in the middle of the screen. Anytime I move a window and it crosses this guide, the guide becomes visible because the window contents become distorted.
Isn't tearing exactly what Beam Sync prevents?
Perhaps I'm misunderstanding the terminology here, but the "breakup" described in the post above appears to be describing tearing (I think that's the common term), an effect that happens, basically, when the monitor switches from drawing one frame to the next in the middle of a screen refresh--the top half of the image is one frame behind the bottom, basically.

Thanks, I appreciate the informative response. The word "tearing" escaped me while I was posting. You make a good argument for leaving Beam Sync enabled. I do remember playing full screen videos in 10.3 and witnessing some tearing. I don't however remember window tearing being that drastic though. At least nothing compared to the tearing I used to see in X-windows under Linux, or after I turned off Beam Sync as described in the hint. Also I thought Double Buffering helped prevent window tearing?

Yes, I second: beamsync prevents tearing. Double buffering only prevents tearing if the buffer is copied to the screen in sync with the refresh rate.

Using Quartz Debug was part of the original hint. Downside was you had to force quit the program in order for the settings to stick, otherwise they would revert. |
