I've noticed some weird behavior with the "real time" modifier-labels when targeting an enemy in combat. Not sure what to call them, but I'm talking about those red or green labels like "GWM All In" or "High/Low Ground" that will pop up underneath the enemy's name when you hover your targeting cursor over them. These will blink in and out in rapid succession for me sometimes - almost looks like they're flickering. First noticed this when I was using my then-current campaign after the update ... which I had started before patch 8 had dropped. So I thought it might be an issue caused by using an older save-game. I've since started a new game and that behavior is still very much a thing.
I've also seen some weird stuff with moveable objects in the world vibrating like crazy (wooden boxes) - something I'd never seen in this form. I know characters will sometimes slightly vibrate under the "right" circumstances, but this looked much more spectacular than that. This was so bad apparently that I couldn't loot or even move said box (it was one of the ones in the Blacksmith's cellar in the Blighted Village). The only way to loot it (and make it stop vibrating) was to have Lae'zel hit it with her axe..

Also some weird behavior when trying to use Jump - though I'm not sure this one is new.
Was going to loot the storage room in the Goblin camp (the one with all the smokepowder barrels in it), sent down SH who then built first a two-box then three-box "tower" for my Tav to jump on. This usually works 100%, but while Tav would enter her "ready to jump" pose, she wouldn't actually jump when I left-clicked. Tried different spots in the world and on the same level as her but she would never execute the jump. UI was "locked" when she was in jump-mode and I would have to press RMB to cancel that mode and enable the UI to accept other input. "Fixed" this by doing a quick-save then immediately reloading. After that she would jump down onto those boxes just fine.
