What are your display settings and screen resolution?
Resolution is 1920x1080 and scaling is 125%.
Thanks for writing. Does the same happen to you using, for example, Dolphin?
Not in dolphin nor Okular, only in Krusader and now I also noticed the same thing in Lokalize. There needs to be something like "QGuiApplication::setAttribute(Qt::AA_UseHighDpiPixmaps);" in the code but I don't know what. It's not "...AA_UseHighDpiPixmaps", it's does something, but it doesn't fix the issue.
This is fixed in master branch and will appear in v2.8.
