KDE 菜單字型太小無法閱讀

在 3840x2160 解析度的 Linux Mint 20 Cinnamon 16:9 oled 螢幕上，kde 相關應用程序（KWrite、ktorrent、digiKam、Gwenview、anki、Dolphin）的菜單字型太小而無法閱讀。下面是 libreoffice 正確大小和 KWrite 不可讀字型大小的比較：

系統圖形界面中字型大小的增加沒有影響。

字型如下：

Default font:  Ubuntu Medium 10
Desktop font: Ubuntu Regular 11
Documents font: Sans Regular 11
Monospace font: Monospace Regular 11
Windows' title font: Ubuntu Medium 11

text scale: 1,2
Optimisation: complete

在全新的 Mint 上，字型的大小是正確的——更大的。

比例因子必須為 1。我猜這是 KDE 和 Mint 之間的錯誤。
