This was substantially improved in Bug 376848, but maybe not enough?

Hi, yes, I'm with you (@Nate).

Thanks for the improvement (done in https://bugs.kde.org/show_bug.cgi?id=376848), but it really seems not to be enough.

Just put eg. a photo on the Desktop, put Dolphin (file manager) aside and compare both results. The thumbails in Dolphin look pretty (smooth and sharp). 

Instead, on the desktop (folder view), they look kind of blurred (and make me think that I need new glasses ;-) ).

Regards, Gerhard

See the discussion at https://phabricator.kde.org/D10223#203166.

It's pretty simple to fix this by making landscape images shorter, but harder if you want to preserve the behavior of landscape images being tall.

Patches welcome. :)

Blurred icons in taskbar, too

Besides the desktop, this image shows the same happening in the taskbar, but not in the start menu.
