Devices not showing

Guys, I have HA with the following setup.
System Health

arch armv7l
dev false
docker false
hassio false
os_name Linux
python_version 3.6.5
timezone Europe/Nicosia
version 0.95.4
virtualenv true

Lovelace

mode auto-gen

My problem is that I cannot access all the zwave devices under my zwave tab in 100% zoom of chrome. I cannot move slider bar up or down
image

With 80% zoom all the devices are there. It is like in the 100% the devices are under the blue top bar.


Bug?

Yeah there’s a few polymer bugs like that. Try the up/down arrow keys.

I tried already with cursors and it worked. Do we need to open a ticket for this?.
Is it known?
