When installing the ThinLinc client on the latest Igel OS, the icon placed on the desktop is slightly blurry. It looks like it gets scaled up a bit.
A crude measurement suggest that the icons on the desktop are 64×64px. But our included icon is 48×48px. So that would explain things.
There might be other cases where the icon is also blurry. It was just the desktop icon I noticed right away.
