Thanks Alexandru, is the flicker you are referring in the background the number of columns changing?

If so that is to be expected, and I cant see a different flicker

Hello! I attached a frames gif to be sure. In this video, it can be seen that when changing from 4 rows to 1 row, after confirming, the 4 rows option is still displayed for a split-second and then changed to 1 row so I think that is what's causing the flicker. If more information is needed please let me know. Thanks.

This gif shows the frames changing as well (see comment 2). Sorry for the spam.

Just doing a bit of triage, and this one came up.

I looked a bit into it, looking at the gifs and testing it locally.

I think if I understand this, the Flicker and issues I see in the frame gif looks like it's attached to the dropdown itself, which I think is a OS level UI. The dropdown box looks different for me than it does for you in your recordings, I don't think I see what you see, and I don't think we can fix what you're seeing. If I understand what's happening in your clips.

Yes, this is about the dropdown, there is a split-second glitch displayed when changing between number of rows. I see that this is most reproducible when changing between 1 row and 2 rows using the keyboard.

I was able to reproduce this today.

For me it happens when I go from 1 row to 4 rows, it looks like it cycles between all rows until it hits the target. If it happens to be going from 1 to 2 rows, I don't see any flicker. But from 1 to 4 it's super obvious, it very quickly goes from 1, to 2, to 3, then finally to 4. I can trigger this with the mouse too.

Ah yes, I can trigger it now from any row, even 1 to 2.
