Scrolling and moving the cursor over the file portal's contents

SUMMARY
Icons have issues with rendering when browsing through contents of a directory using the KDE File Portal. The icons are pixelated and strangely alternate when hovering over them. 

STEPS TO REPRODUCE
1. Open KDE File Portal from any application.
2. Observe different icons of the folders, files, folders with preview etc.

OBSERVED RESULT
The icons in the file portal appear pixelated and hovering over them makes them alternate in a strange way. See attached video and screenshot for reference.

EXPECTED RESULT
The icons appear clearly and don't alternate when hovering over them.

Might be related to https://bugs.kde.org/show_bug.cgi?id=479891 as the temporary fix mentioned there, involving QT_SCALE_FACTOR_ROUNDING_POLICY, has solved this problem as well.
