Description Zamundaaa 2021-08-29 16:32:13 UTC 
It looks as if GL_NEAREST was used; text and icons are pixelated and often cut off.

scripting: Make thumbnaills use linear filter

QSGImageNode ignores QSGTexture's filter, one has to specify it using
QSGImageNode::setFiltering().

In hindsight, we need to figure out how to integrate the lanczos filter
with window thumbnails and use it instead.
