Please describe your issue in as much detail as possible:

For quite some time Steam client for linux cannot remember some settings. There may be more of them but i am listing here only those settings whitch i am changing. On Windows is no problem and Steam client saves all settings.

It is known behaviour that if i delete download cache from settings, Steam client will restart and open on account selection page. After logon back, some settings are reset to defaults.

I have observed this on following settings pages:

Interface:
"24-hour clock" toggle will turn back off
"Start Up Location" will revert from Library back to Store

Cloud: - "Screenshot Management" toggle will turn back off

In Game: - "Toolbar Preferences" will completelly reset and enable all toggles

"Game Recording" - you have to click again on "Got it" like first time when it was a new feature

There may be more settings which are not saved, but i have observed only these which are my preferred.

Steps for reproducing this issue:

1. Logon to Steam client
2. Change described settings
3. Clear Steam downloads cache, logon back after client auto-restart and check those settings. They will be reset to default.
