I have a Windows 11 PC with a 27" 1440p monitor. I have to use a DPI scaling of 130% in order to get text and windows applications to be large enough to actually see. This never caused an issue with WoW in the past, but ever since the pre-patch, WoW isn’t working so nicely with it.
It seems that any UI element added in 11.0 is scaling by my DPI scaling, instead of the ingame scale. These elements include: the login screen, the talent page, the raid assistant sidebar. It has negativelyt impacted my experience, and I am especially frustrated as I reported this issue all throughout beta and here we are 
I have talked to other members of the community and they have this issue as well. Please Blizzard, let us know that you will fix this. It will only get WORSE as more players get higher resolution monitors. I’m sure the 4k-ers are having an even worse time than me, since they need to scale much higher than 130%.
