I don't call text which is significantly too big or too small legible. When apps that use different toolkits perform different font size adjustments, the resulting UIs are inconsistent and generally tiring (uniformity is a huge factor in text readability) When basic font sizes are out of whack because the desktop pretends the pixel density is way different than it is really users try to compensate using all the available size settings in their apps. The result is a huge heterogeneous mess. Settings and documents can not be moved from one computer to another without strange font size changes. Different fonts are not adjusted the same way by users, because of size rounding in UIs, breaking font set harmony. Sometimes you get apps that adjust via zooming without re-rendering -- Nicolas Mailhot -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
