app is glitching and data is flickering

[gpopesc]

I am using in docker in a Synology NAS DS218+ and I noticed following problems:

1. When I press to show daily or weekly statistics, the web interface is showing few seconds the correct data then it shows back the hour statistics and so on. The same, if I select an application it shows the app data for daily, after few seconds it shows back the statistics for all apps.
2. The web interface is glitching (probably because of slow processor of my NAS) Ideas:
3. There is no back (or home button) after selecting one app and go back on first screen to select another app.
4. Maybe you can set dynamic scales for some apps (if they use low memory, network, or processor, you can not really see the corresponding figures from graphs.
