As I have stated in the title the loading icon animations are seem to be freezing. I have experienced this in the AppCenter update tab and during the Wi-Fi connection. However after a while the processes are completed. Is this issue related with the Loki update ? Do you know any bug report for this issue ?
I have not seen a bug like this (then again, I rarely look at the bug reports :P ). Could this be a graphical glitch? The system may be doing a large update, and it requires a great deal of system resources. This could be what's causing the freeze: the system can't properly draw the animations due to the use of the resources.
