Bug in Taskbar

[isn99]

When I occasionally press the "Always on Display" on the taskbar for a long time I get a notification that is slapped, you can see it in the picture. How can I fix it?

Try this!

Wipe Cache Partition.
Turn off phone.
While powered down, press power key and volume up button simultaneously until the phone vibrates. Let go of buttons. You will now be in the bootloader. Using Volume buttons for scrolling, power button for Yes.
Scroll down to Wipe Cache Partition. Press power, scroll to Yes, press power. Reboot press power key.

I think you gave me the same information on another problem a while ago and it worked, but with this one it didn't work.

You can submit a error report to Samsung. Probably a UI issue.
