When using Renekton's E while having the cursor hovered an enemy, the red sword cursor becomes locked into the blue diamond cursor and causes anyone experiencing the bug to be unable to issue pings or move the camera using the minimap.
Was able to repeat multiple times in one game, and a quick fix is to use Renekton's W while hovering the cursor over an enemy, and move the cursor off before the dash ends, reverting the cursor back to normal.
W is the stun, E is his dash. I noticed this as well... Extremely annoying. Makes it impossible to click the minimap to view battles for TP. Also makes it impossible to ping. Hard to be a team player when you have to scroll over to wards for TP and are unable to ping that your going in.
I usually play Renekton and this bug is f*cking boring, once i had to flash for nothing to cancel this bug !
Finally someone else who also has the same problem jesus. This bug is terrible because not only can you not move the camera when you click the mini map but you cant ping which can lead you to anger your teammates who like to report you over this even though it is not your fault. Also if you have a chat restriction like i do i would strongly advise not playing renekton until this bug is fixed because you will not be able to type out the pings without running out of messages. For some reason that quick fix stated in the original post doesnt work for me so playing renekton is super frustrating even though i love playing him all the time.
