Any workaround for multiple monitors?

I have 3 monitors and it appears the completion dropdown disappears off to the left.

In a query tab in version 12.8.0.6908, when the completion proposal pulldown appears, the top left of the window disappears off to the left past the main monitor, the past my second monitor to make one huge window that I cant see any results in.

Any guidance on restricting this to the main monitor would be most helpful! Thankyou :)

This looks similar to issue #1963, just in the other direction. In the issue the proposal got smaller and smaller each time it was shown.

However, first advice is to reset its dimensions. Please click Tools > "Reset panel dimensions" once. Aftwards, please watch out if the problem comes up at some point, or if it's solved.
