• KOReader version: v2019.03.1
• Device: Ubuntu 18.04 laptop

Issue

When using the bottom menu to set font sizes and margin, the settings are not saved. Restarting the reader resets those settings. The settings show up in the menu where I left them, but the fonts and margins are at their original default.

Steps to reproduce

In Ubuntu 18.04

• sudo apt install libsdl2-dev
• sudo apt install ./koreader-2019.03.1-amd64.deb
• After opening, drag up from the bottom and adjust the font size and margins
• Close KOReader
• Open KOReader
• Note the font size and margins are like they were when the app first started
• Drag up for menu
• Note that the settings make it seem like the larger font sizes and margins are selected, even though these settings are not applied.
