Full screen and multi screen behavior

Hi all,

I recently got a laptop and use an attached monitor. Last week started 
using NB on it (13). Starting a null module project from NB I observed 
some unexpected window handling.I'm pretty sure this is NB and not the 
window manager (ubuntu, gnome). I took a quick look at 
platform/core.windows, and 
.../userdir/config/Windows2Local/WindowManager.wswmgr is interesting.

/Is this expected/, recently changed, exactly where to look in 
core-windows, any insights, ... I won't be able to dig in, at least for 
a while, appreciate any info that helps understand and pinpoints the 
issues, so someone has a head start in fixing the problems.

Weird behavior:

 1. NetBeans comes up in full screen mode on laptop screen. Double click
    title bar, normal mode, size reduced; exit NB.
 2. Start NB, back to full screen mode.
 3. Double click title bar, normal mode. Drag bottom border up to reduce
    height. Exit NB.
 4. Start NB, stays in normal mode, retains size.
 5. Drag bottom to increase height to a little more than it was after
    normal mode in step 1. Exit NB
 6. Start NB, full screen mode.

2. and 6. are bugs (IMO). I don't know if this is recent or long time 
behavior. BTW, at the end of steps 1 and 5, while NB is not running, 
WindowManager.wswmgr shows normal mode (not full screen).

If I drag NB over to the attached monitor, the same type of behavior is 
observed. If the main window gets higher than NB likes, and you exit and 
re-start NB it goes to full screen mode on the attached monitor.

While NB main window is on the attached monitor, dialogs that are 
started usually go to the laptop screen. I say "usually" because it may 
be I moved stuff around, to the attached monitor and NB remembered.This 
recent discussion from users


            [platform] DialogDescriptor/NotifyDescriptor and multiple
            screenshttps://lists.apache.org/thread/7hphr7okvz5qs1q8n3f52nytooc9zs6w

is probably related.
