I have had this issue for a while, and am continuing to have it in Ubuntu 13.10
The bug basically matches the original description- GUI freezes occasionally when dragging a window to the top to resize it. I can't reproduce it on command, but it happens quite often seemingly at random.
Here's my system info I can manage to find
Sony Vaio L Series SVL24114FXB
Processor: Intel® Core™ i5-3210M CPU @ 2.50GHz × 4
Memory: 7.7 GiB
OS type: 64-bit
Graphics: Intel® Ivybridge Mobile
