System Monitor Overview

SUMMARY
The "Applications" section of the Overview window shows blurred fonts when the display is scaled to 150%. Sub-pixel rendering and hinting options make no difference.
Setting the scale to 100% or 125% makes the fonts look okay.
This problem only occurs in System Monitor; the rest of the KDE desktop is fine.

STEPS TO REPRODUCE
1. Set display scale to 150% on KDE System Settings
2. Open System Monitor

OBSERVED RESULT
Blurry fonts in the Applications section of the Overview window (both the new and the old versions).

EXPECTED RESULT
Clear fonts as in the rest of the System Monitor and the whole KDE desktop.
