Absolutely. In all of my time playing, since 2009, I have never had this issue until the last update. It started happened after U59, continued after the hotfix, and persists now. It is not related to whatever is happening in a quest at any given time, as it happens both during and between battles, so does not seem to be connected to high numbers of graphical effects (e.g. many explosive spells).
I have redone the 'detect optimal settings' option for graphics a few times, to no avail.
No system changes anytime near U59 release.
Running 64 bit client.
