Vero 4k update + TV Mosaic max 30fps

Today I updated to the new Kodi 19 version you released. After that Live TV (using TV-Mosaic addon) had slow image and normal sound, so both out of sync. Playing movies works fine. Looking at the System settings, the screen was set to 4k 30fps. I can’t remember what is was before and it has been running great ever since I bought my Vero 4k.
Changing screen settings to 1080p and (around) 30fps, gave the same problem. After setting it to 60fps Live TV was back to normal.
Shouldn’t I have the option to set screen to 4k and 60fps?

We recommend people with 4K TV’s set their user interface (UI) to 1080p. Kodi’s UI is not optimized for 4K yet and this can put unnecessary demands on your device and can lead to a suboptimal picture quality, as well as potentially cause other issues.

The settings we recommend are as follows…

Settings>System>Display>Resolution> 1920x1080p
Settings>System>Display>Whitelist> (empty) *
Settings>Player>Videos>Adjust display refresh rate> On start/stop

Some televisions may also need, or benefit from, the following being set…

System>Display>Force 4:2:2 colour subsampling> (enable)

With the above settings your UI will be output in Full HD and your 4K content will be output in 4K. *Information regarding the whitelist can be found here. If you have any doubt, feel free to upload some logs so we can verify that your settings are indeed correct.

Thank you. That seems to improve things.
Now I need to find out why my Logitech Harmony is suddenly (after update Vero) responding very slow…
