No, I was referring to the pop-up window you get when clicking on the 
spanner icon: that is normal with title bar.

The problem is with the main plot window. It is connected to the boolbar 
but the two a stuck at the top left corner of the screen

Ah! In attempting to get more detail on the question of the frame , I've 
found out what was happening. The WM was placing the window with the top 
of the toolbar at the edge of the screen , thus hiding the titlebar off 
screen,  meaning the window could not be moved. I still had the right 
and bottom frames to resize but could not get off top-left corner.

I managed to grab the top right frame corner and resized downwards at 
which point I realised the titlebar was there but not accessible.

Now it is placing the new plot windows bottom-right instead.

This may be a DM quirk with lxdm but I have not seen any odd behaviour 
with other programs  All other windows fall within the visible screen 
and respect the window free margins defined in the DM ( I use 10 px 
right hand side margin for mouse scrolling between desktops ).  I use 5 
desktops and slide windows from one to the other without issues.

It may be specific to lsdm but I suspect gnuplot is not setting ( or 
mis-setting ) some window parameter, ie providing the plot window 
coordinates instead of the frame coordinates.

There is intelligent window placement on this DM which generally makes a 
good job of finding the clearest bit of screen to open a new window. 
Things like terminal windows which do not retain a 'last used position' 
usually end up against one of the four corners. They never end up with 
the title bar hidden.

All this works perfectly for everything I used except gnuplot

I just tested the dsitro packaged gnuplot and it does not have this bug.

gnuplot                    x86_64             5.0.1-2.fc23


Uninstalling and reinstalling CVS I have the same issue again.

Hopefully that gives you a clearer picture of what is happening.


Now I have found out where the titlebar is , it is just a minor 
annoyance and does not prevent me using qt terminal which is great. I've 
been using wxt ever since I install gnuplot and would like to test qt 
which I did not have on my old system.


There definitely is an issue here, though not a major one. Whether this 
is a regression or something that Fedora have fixed, I can't say.

Thanks , Peter.
