--- Comment #3 from Dmitry Timoshkov dmitry@baikal.ru --- (In reply to Artem S. Tashkinov from comment #2)
Tahoma size <=6 is also antialiased.
So, fonts sizes from 7 to 13 are not antialiased while all others are antialiased.
I don't have a fontconfig configuration file for that. For my native Linux applications all fonts sizes are antialiased.
Looks like a limitation imposed by a 'gasp' table, that's not a bug at all.
