Subject: [PATCH 13/22] Paint: Enable subpixel text positioning by default
|
|
|
|
On desktop Linux, subpixel text positioning is necessary to avoid
|
|
kerning issues, and Android is no different. Even though most phone
|
|
displays have relatively high DPIs, the lack of subpixel text
|
|
positioning is only unnoticeable on high-end devices such as the Pixel 4
|
|
XL (1440x3040 @ 6.3 in => 537 dpi).
|
|
|
|
For example, on the Pixel 5 (1080 x 2340 @ 6.0 in => 432 dpi),
|
|
horizontally-scrolling labels in QS tiles can be seen "jittering"
|
|
slightly upon close observation. This was tested with the Google Sans
|
|
font on Google's stock OS. At this lower DPI, there is still a need for
|
|
subpixel text positioning (at least in some cases).
|
|
|
|
Enable subpixel text positioning by default to fix occasional kerning
|
|
issues and jittering when text is in motion.
|
