This behavior is really annoying and distracting.

I have setup my computer to use the mouse pointer with autoselect. When I hover over an screen is selected. This function works as intended.

PlSQL Developer in the other hand when I change tabs, it redraw itself in less than a second. The whole window disappear for a fraction, it is not perceptible for the human eye, but my mouse picks the windows that is behind plsql developer.

Anyway to prevent that? is very annoying to have to look for the window every time it redraws. Also, it makes slower changing tabs.

Are you referring to the "Activate a window by hovering over it with the mouse" option from the "Ease of Access Center"? I tried this option, and do not see any issues.

Perhaps you can send one or two screenshots to visualize this?

Yes, I am referring to "Activate a windows by hovering over....." from the "Ease of Access Center".

I am pasting a link for a little video replicating the issue.
It only happens with PLSQL developer and any other window open that is behind PLSQL. This behavior does not occur between any other windows.
1. I am showing there are 2 windows. Browser and PLSQL
2. I clicked in the first tab and then click another tab within PLSQL
3. I do step 2 several times until PLSQL "refresh" and the window (web browser) is picked by the auto select cursor.

This redraw thing has different behaviors through the application. I called it redraw, probably it is not that, but I couldn't find a better word.

It also affects when the application was minimized and you call it again, redraws very slowly. You can see it in the next video click on the link.
Something similar but worse (slower) happens when in the mornings you connect it takes a lot to comeback. Also, when you have a workset and load it. It takes a lot of time to redraw the tabs.
