Hi, I have had a problem with the correct display of the thermostat card for a long time. Since some older update, the card graphics are still bad. Thank you for your help!
If that is a standard card without any custom styling you should open an issue here:
Sure, I wonder if the same thing is happening to someone else. Cards are without their own styles.
I found some advice on github and I tried to find out that the problem is caused by the mini-graph-card https://github.com/kalkih/mini-graph-card. After removing this extension, everything is fine.
