Featured image unstable

Is it the theme or the plugin, both are busy with the featured image so I made this report as well:

Hi defensiefotografie,

Thanks for reaching us,

I suspect one of the plugins you’re using might be causing the problem, so please try deactivating all?the plugins one by one and check if the problem resolves.

Since last update of Colormag, it looks more stable.
Thanks. Issue marked as resolved.
