UPDATE: As of WindowBlinds 10.56 Beta, the issue has been fixed.
I'm not completely sure whether this is an issue with WindowBlinds or with the styles themselves, but it affects quite a few styles on my 4K display. I've been experiencing this for months, but I generally just ignored it, until today, when I noticed a few things that I hadn't noticed before. The problem is that it is impossible to resize windows from certain edges. The edges that won't resize vary depending on the applied style, but usually any thick edges are not affected by the issue. That leads me to believe that edges below a certain thickness are not being scaled up enough, resulting in edges that are too thin to be grabbed. Furthermore, this problem occurs when the display resolution is set to the default 3840x2160, but not when it is set to 1920x1080.
I tried using SkinStudio to adjust the window frames, but I haven't had any luck with it so far. I made the edges thicker, but it still did not solve any problems.
Styles that I tested:
- Resize not working properly: Ansaro, Aragon, Coal, CompleX, Dark Realm, GrayTex, Shimmer, Trexal, Vantage, Diamond, Echo, The Captain
- Resize fully working: Beyond, Crux, Digital, Talix, Steam System - Gray, Alpha Alpha, Soft Blue, Tech I, Unify, Acrylic 7, Corporate, Eva, Ice, Lantana, Modern, Precision, Win8, Win8 Metro
I've posted a screenshot that shows an example of the issue (theme is Ansaro):
