I work on a laptop with an external screen attached.
When I switch between Duplicate and Second Screen Only, it takes 10s+ for PlSql to finish resizing itself!
While this is ongoing, the elements of the window keep jumping around and redrawing.
This is painful; I do this regularly when I need to share my screen.

Also, when the window size is reduced, the result in a SQL tab can become below the visible area, so I can't drag it up.

If I change to "Extend" instead, and drag the window between the two screens, there is a ~4s delay each time the window passes the half-way mark.

Regular resize also seems a bit sluggish, and it seems to get worse when there are more tabs open?
When I started writing this post, each resize took about 2s, but when I closed tabs and reopened, it is more like 1s, so not sure what is going on there.
But, at least if only 1 mostly empty tab is open, the resize is more or less instantaneous.

With the laptop connected to the external screen, can you go to Help > Support Info and send the text from the "Info" tab page to support@allroundautomations.com?

Done

Thanks. I see that one screen has a 100% scale and the other has a 125% scale. Can you make them the same and check if that helps? Either both 100% or both 125%

Both screens had the "recommended" scaling, which was 125% for the laptop. Assume that was default as well.
Changing my laptop to 100% solves the problem! Now I can drag between the screens, or switch between "External Only" and "Duplicate" with no apparent lag. Nice!

For me this solves the problem, since I rarely use the laptop screen.
For those that do use the laptop screen, it might not be acceptable to make everything smaller.
