My bug seems similar to this one but I don’t believe it’s been solved by the webflow team quite yet. I will try the temp fixes but if anyone has more insight it’s appreciated. Basically, when hovering over my grid in mobile view (especially near the bottom) it starts to glitch. Other people have said this has something to do with hover states or nonexistent grid frames but I don’t see that in my case, this seems like a complex bug to me.
Here is a video, the glitch happens in the designer, as well as, in the preview and on the staging site: https://www.useloom.com/share/173e008d8a164d25910b3fe26ce85d2e
UPDATE: I was able to find a workaround fix just by deleting the glitching grid element and then recreating it with the same classes I had created for it. I hope this helps others, thanks @davidvm for the tip.
