Terminal text example.

Reddit is a gold mine for bugs. So the preview in the task manager is way to pixelated even if it text as big as the preview text is put right next to it.

Oh yeah, much better. Should I expect this to be implemented soon?
Comment 3 Eike Hein 2018-02-14 15:05:19 UTC
It's still under revision (the latest work I've seen is again much better than the screenshot shown there), but I expect it to make 5.13.

windowthumbnail: Use mipmap texture filtering

Blit the contents of the TFP texture to a separate mipmap texture,
and (re)generate the mipmaps on each damage event.

This commit also fixes ARGB thumbnails being rendered as opaque.

Note that this commit only modifies the GLX path.
