Same behaviour when using sandbox vault, but sandbox vault is not suppose to keep changes, so I guess it is as expected in this case. Don’t think this particular issue can be tested using sandbox vault.

Expected result

Zoom level setting is retained after Obsidian restarts or reopen the vault.

Actual result

Zoom level reset to default value (100%)

Linux: Zoom Level / Zoom Factor is not restored on startup

Since installer version 1.9.10 / Electron 37, the zoom level settings works but is not correctly applied / restored on startup under Linux. This seems to be an upstream regression of Electron.

Any workarounds? Method suggested in Keeping zoom level between sessions - #3 by reonnard (CSS snippet with body { zoom: 144%; }) does not work for me.

I have found that running Obsidian with Wayland appears to retain the zoom level after restart:
