Should not matter for this issue

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

This has been an issue for a while

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).

After doing some more research, it turns out this is an issue with UI scaling on 1440p monitors.

This post describes the issue very well:

Essentially, to get a pixel perfect UI scale, you need to divide your monitor's height by 768 which results in 0.53 for a 1440p monitor.

The lowest we can set our UI scale is 0.64 by default.

We can set it to 0.53 using cvars which fixes this kind of issue with the uneven borders, but then every UI element is very small and needs to be scaled up using Edit Mode or in the case of Classic, using something like MoveAnything, which isn't ideal.

We can also set our UI scale to 1.0 which fixes this kind of issue, but then every UI element is very big and needs to be scaled down.

Looks like nobody at Blizzard has a 1440p+ monitor or something.

Yes, according to blizzard this is a game feature. You can try to setup a bigger border size to aleviate the issue too, Grid2 allows to setup decimal values to the border for example a 1.2 or 1.5 border size (you have to manually type the number in the editbox under the border size slider)

Thanks @michaelsp

I'll try the decimal values for the borders to see if I can find something that works no matter which group size I'm in.

You can close this issue since it seems like it's on Blizzard to fix this.
