Pretty much always when the update notification shows up, there is some weird jank, like first showing part of the UI and then changing it a bit.
But there are also worse cases, like the one attached.

Oof, that looks pretty rough. This seems like either a panel, graphics or widget bug. I'm going to put this in Widget:GTK right now (since it looks like you're using Linux).

Like it looks like an invalidation bug. So actually, maybe this is more of a Graphics thing.

Could this be a regression from bug 1635153

Comment 5

[Darkspirit]

Yes, most likely, if you are using X11 and if it's a recent regression.

Has this been fixed or does it still occur? (first good build should be 20200801094810)

This is a rather bad UI glitch.
I wonder if this is gfx or frontend. Why would there even be two different states (or two different popups?). One should show the popup only once it is ready to be shown - if that is not the case, this could be frontend issue.
