Dynamic Lighting ctrl+L not working etc.

I have been using Dynamic Lighting option for almost a year on and off.. (only when I really need it) so I'm kinda used to it by now,..suddenly for the last couple of days I have started to have issues with it... Usually when I placed a token (aka "Torch" or whatever) that emits light, I placed a players token that has set to have sight in the same room to check whether and what he sees using ctrl+l... now when I do exactly the same thing, and press ctrl+l on selected players token - nothing happens. I tried to rejoin as player with granted access to this token, but all I see is black darkness with my token in the middle. I have tried multiple combinations with thick-boxes at map settings where Dynamic Lighting options are,..I have tried every possible way in Token settings but no success... so I have come to conclusion that this might be an annoying bug. I saw that similar problem was reported 6 months ago already, but the topic is closed.. so I initiated a new one...  Thanks! Also.. LoS not work as well, after I mark the lines in Dynamic Lighting layer.... Restrict movement does work though..so..weird.

One known issue is that if you're using chrome and you have Hardware Acceleration disabled, DL won't work. For info on how to enable it, see here: <a href="http://www.webupd8.org/2014/01/enable-hardware-acceleration-in-chrome.html" rel="nofollow">http://www.webupd8.org/2014/01/enable-hardware-acceleration-in-chrome.html</a>

Thanks,..switched to Mozilla and it works there.. (despite the fact that R20 in Mozilla is not performing as smoothly :/) Tried following the guide on how to enable this Hardware Acceleration thing, did everything it suggested, but Chrome still does not like DL.. oh well.. seems like I'll stick with Mozilla then.. Only one thing.. if players have also disabled it.. does that mean they wont see anything on the map? :p Fun Fact: It started to work in Chrome about 3min after I posted this.. so..I guess it works now.. Thanks for fast reply.

Yep, Dynamic lighting requires the hardware acceleration to be set appropriately and requires javascript to be enabled and properly updated. If either of those aren't true for a user, the feature won't work for that user but will still display correctly for everyone else.
