With the new U.I, the u.i flickers when you open a bag in the inventory, if you right click and drag to see around the room its very choppy. When you use WASD to move around it is not choppy, kind of odd this is a new issue. The U.I also does not feel very responsive either, when you open the inventory window there is a delay to it as well, minor but it is there. I am on a RTX 3090 AMD 5950x machine with 64 GB of ram, NVME HDD and gigabit internet.
Same issue on my 12th Gen Intel(R) Core(TM) i7-12700KF 3.61 GHz with 64 GB of ram. NVIDIA GeForce RTX 3060 Ti Samsung SSD 860 EVO 1TB Windows 11- 64 bit
It's mentioned in other threads since the patch. Try reloading the client today to see if todays hotfix, fixes it. [edit] I just now confirmed that the flickering seems to be fixed.
