I do not know if anyone besides me is facing this problem or not. Since I have installed this version Ubuntu Mate 22.04, I am facing a strange behaviour from the applet panel after customizing it and reboot or booting my device. The menu icon gets rectangular shape or blare. Once I enter properties and change this icons size, it runs normally and appear the correct shape for the menu icon, and that also do on the clock and language change.
Each time I have to do this method once I turn on the device or reboot it.
Does anyone face this problem !!
