To reproduce, run: Tools/Scripts/run-webkit-tests --wpe animations/negative-delay.html --iterations=1000 Same with --gtk. Memory usage for WPEWebProcess will go above 1GB very quickly. Reverting that patch makes WPEWebProcess stay at about 35 MB of RAM. Zan proposed the patch in http://sprunge.us/JBei but with this patch memory usage increases nonetheless to about 100 MB, so there is still something else not being released. I am not familiar with the coordinated graphics code so this is as far as I can go.

Comment on attachment 311723 [details] Patch Yep, works.
I can't comment as to the patch itself, but I tested it and memory remains under control with it.
