window resizing slow/broken on compiz resize setting 'normal'

[Tim Clifford]

Ubuntu 12.10, ATI fglrx drivers (13.3 beta), running CompizConfig and setting window resize to 'normal' makes window resizing hog the CPU and extremely slow to the point of breaking other effects. A quick google search brought me to this bug report:

https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/803296

where the mods kept saying open a new bug report, so here I am. Click and drag on the side of, for example, chromium with multiple tabs open, can hang the computer for 15+ seconds when trying to live-resize, but after a few passes it starts studdering for as little as a fraction of a second between screen updates.

I'm very interested in work-arounds as window-resizing is super important for my day job (making responsive websites), and currently my workaround is to guess a lot using non-live window-resize settings, and then boot into Windows for double checking and finalizing. And, come on, it's 2013. No one should be booting into Windows anymore.

I hope this is helpful and leads to stamping out errors in the compiz window-resize code for good! Best of luck!
