I just installed Kali Linux Rolling and I run apt-get upgrade. When it finished on the tweak tool on the appearance tab in the cursor option, I get this text Adwaita [][][][][][][][][] instead of Adwaita (Default).Also on the system monitor on the processes tab, on the memory column, on the process that ram status is N/A I get this text again [][][].
