Hello, I try using Kubuntu NEon with actual Plasma, but I must using larger scale for UHD monitor. In old Plasma for Kubuntu 18.04 is OK, but new Plasma show bad scaling icons for right click menu. see screenshot.

Does this happen with the default Breeze icon theme?
Yes Breeze make the same thing. But also toolbar icons is blurry.
What does "Kubuntu NEon with actual Plasma" mean? Are you using KDE Neon or Kubuntu? How did you set the scaling? With System Settings > Fonts > Force Font DPI or System Settings > Display and Monitor > Scale Display? Does this only happen in Dolphin, or in other apps too? Does it happen in Plasma as well? Can you attach a screenshot of the problem happening with Breeze icons?

Thank you for your willingness. I must set scale to 1.5 and font scale 140.
