  2. Join a raid and wait till people join/leave the raid

  3. Frame size is not  changing when people leave and join 
Did you try having Grid2 as the only enabled addon and everything else disabled?

  yes  same behaviour

Was it working in a previous version? If yes, which was the last good one?

 dont know the last good version, i think it was 2.6.7

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).

  no lua error

Please provide any additional information below.

 There are four ways to calculate the raid size, Which raid size calculation method are you using ?

Keep in mind that:

  - Frame size cannot be changed in combat, so if you are in combat the size change is delayed.

  - If the "Display all groups" option is enabled (This option is in Layout/General), the addon will always assume a 40man raid.

Thats some helpful info! I also just saw the a fix in the changelog.Thanks a lot for your awesome work!
