Frankly, I don’t know how to check whether Emacs uses Xwayland. If I compile with --with-x I would expect it to do always, but is this the case? > And are you sure that what you see is really because subpixel > anti-aliasing is not being performed, and not because your hinting > preferences are not being respected? What I do is pretty crude: I make a screenshot and look at it in Gimp heavily magnified. With pgtk, I see only greyscale at the rim of the glyphs, and without pgtk, I see pixels of various colours (greenish/reddish). This coincides with my subjective observation that in the latter case, the text is crisper. I do see subpixels in the menu text of other applications as well as in the Chromium browser, in the same Gnome session as Emacs. Regards, Torsten. -- Torsten Bronger
