X11 without blur
The virtualbox in the screenshot is an example of blur, the plasma looks the same blurry. This happens because You are using a high DPI scale factor but the app in question is not Wayland-native and instead uses XWayland. XWayland is not able to use the app's X11-specific scaling support, so the result is blurriness. This needs to be fixed in one of the following ways: 1. XWayland gains support for X11 scaling 2. The app becomes Wayland-native All of these things are outside of KDE's control, I'm afraid. No, Plasma is blurry too. Right, in addition to XWayland apps being blurry at all scale factors above 100%, even native wayland apps like Plasma are blurry at scale factors other than 100%, 200%, 300%, etc. It's also a Wayland protocol limitation at the moment. The bug is also present at a scale of 100 and 200%. Please attach a screenshot showing blur at 100%. Hi, you're right. I took 2 screenshots in X11 and Wayland but couldn't see the difference. The bug can be closed. |
