WowAce

What version of Grid2 are you using? Grid2-r955 (latest version on Twitch)

What game client version (windows or mac) and language are you using ? Windows

What steps will reproduce the problem? Nothing specific--it randomly occurs when in a group of any size

  
Did you try having Grid2 as the only enabled addon and everything else disabled? No, because then I can't heal properly. I'm using Grid2 + Clique

Was it working in a previous version? If yes, which was the last good one? I just returned to retail after a long hiatus; however I do use Grid2 in Classic and there are no issues. 

Do you have an error log of what happened? If you don't see any errors, make sure that error reporting is enabled (`/console scriptErrors 1`) or install [BugSack](https://mods.curse.com/addons/wow/BugSack). I don't have a log. I can install the error addon and try to see if it's catching it. 

Please provide any additional information below.

Ok, so. Randomly one or more of the unit frames will disappear off the screen. This isn't a 'fade for range' thing, the entire area where the box is for a specific player (occasionally it's been more than one player) will just go completely blank. What's weird, is that I can still click on that blank space to target the player and can still mouseover heal them in the blank space. So....like, the frame still exists, all of the visual data just temporarily disappears. It will then randomly pop back into being. This seems to happen more frequently in combat, but also occurs out of combat as well. 

I love Grid2 and am really comfortable using and configuring it, so I really, really, REALLY do not want to have to switch addons for my unit frames, but as a healer having the visual of my party members just randomly disappear is untenable. 

Disable other addons, Try with another profile. Probably not Grid2 related.
