Configure Gwenview antialiasing of thumbnails?

Is it possible to configure antialiasing settings of thumbnails in “Browse” mode (thumbnails grid) of Gwenview? I’m using it to review technical drawings and right now some lines become invisible at certain scales. Configuring it would help me a lot.

ok, if you go to
open menu > configure > configure gwenview > advanced > low resource usage mode
ticking it ON seems to force antialiasing in browse (preview grid) mode. It’s a bit slow, but it may be just good enough.

I don’t quite understand though why it’s not happening by default.
