Enable /hideall in all events.
 

My computer for some reason has a terrible time handling the text/effects within Graal. Nicks/chat/lights etc slow down my client so much that it takes me 2 minutes or so to walk across one level. It gets terribly annoying and there is no way I can play a game like that. Some events allow the /hideall command, but a lot of the others simply do not, so I can't play them. I suggest that you enable that ability in all events because it really helps people out (like me and many more). Even today I realized /hideall doesn't even work in some events it used to (at least on my client) making it somewhat unfair. So I suggest you fix this please.

Might be helpful if you list the events it doesn't work in.

Dodgeball
Mushroom Catch
(today it didn't work in ttpk or mazepk but it usually does)
Figure Skating
lucky guess
(most pk events have /hideall)
number guess
pictionary
etc etc etc. there is a lot of them . but today it wasn't working in any for me.
