I am having trouble using the default qt graphics_toolkit in Octave since at
least 7.2.0.
Curently I am using Octave 8.2.0 with Windows 7 SP1.

I saw bug # 62660 (also # 62661) and it's solution to use setenv('QT_OPENGL',
'desktop') 
seems to be on the right track, but doesn't fully work for me.

Specifically,  Octave quits working and I get the Windows dialog-box-of-death

"octave-gui.exe has stopped working"
in one of two ways:

1) Immediately after Octave starts, I can run 

   setenv('QT_OPENGL', 'desktop')
   % without error but as soon as I then try to run
   plot(1:10)

   the dialog-box-of-death occurs. [fn1]

2) After starting Octave, I can switch to fltk via

   graphics_toolkit('fltk')

   I can then

   plot(1:10) % and get the expected plot, and then 
   close % works as exected.  I can then
   setenv('QT_OPENGL', 'desktop') % and
   graphics_toolkit('qt') % without error.  And now I can even 
   plot(1:10) % without error and get the expected plot with toolbar and
working mouse coordinate tracking.
   % But ... when I then
   close

   The figure does close, but I get the Windows dialog-box-of-death. [fn2]

If immediately after Octave starts I try

plot(1:10)

A figure gets created, but nothing gets plotted.  Then, clicking in the figure
displays

warning: opengl_renderer: Error 'invalid operation' (1282) occurred drawing
'text' object
warning: opengl_renderer: Error 'invalid operation' (1282) occurred drawing
'text' object
warning: opengl_renderer: Error 'invalid operation' (1282) occurred drawing
'text' object
warning: opengl_renderer: Error 'invalid operation' (1282) occurred drawing
'line' object
warning: opengl_renderer: Error 'invalid operation' (1282) occurred drawing
'axes' object

I can then 

close

and the figure gets closed and Octave continues.
   
Thank you for your prompt attention to this matter or letting me know a
workaround.
