Can you attach a screenshot of the brokenness? Is this a recent regression?

I noticed this only a couple of days back, but I dont know if this was broken before too.
I am willing to do a regression/bisection. But I will need detailed steps on how to do it. I am familiar with the GUI version of the moz-regression tool on Windows.

You need to enable USB debugging in your phone's developer options and plug your phone in to the computer. Then in the mozregression GUI click the scissor icon to start a new bisection. On the first screen there should be an "Application" setting, where you need to select gve instead of firefox. After that it should work as normal

Summary of the discussion so far :

1. This bug is reproducible on a build from 2023-Feb-25 . The borders mau have been broken for a longer period of time.
2. I am trying to get older builds (say Sep2022) to get to the first "good" build for a regression. But moz-regression GUI on windows cant download a build earlier than Feb2023.
