Steps to reproduce the problem:
1. open Chromium
2. Press Alt-Tab to show Task Switcher
3. 

What is the expected behavior?
Show 128x128 sized logo.

What went wrong?
Icon of chromium is blurred and upscaled.
This is a duplicated bug of  Issue 459354 . However, that bug is already closed because of inactivity.

I meet the same issue in version 51.0, plasma 5.6.95.
I hope chormium can use 128x128 sized icons as default. It is an easy fix, just apply the following patch.
