LVGL 8.3.0 displays better font than 8.3.9 with LV_COLOR_DEPTH=8

After LVGL was upgraded from 8.3.0 to 8.3.9, it seems that the fonts display became worse.

There is no change in the lv_conf.h file before and after the upgrade.

In lv_conf.h, LV_COLOR_DEPTH is defined as 8.

Any hints for this problem?

“disp_drv.antialiasing = 1;” is the solution.
