I noticed in v 6.0 that now the screen size jumps when I select
certain tools. It is because of a change in size of the second
toolbar row - the one that shows the line thickness when you are
placing a line. This toolbar is adaptive. It shows the relevant
options for whatever tool you happen to select. And in some of those
adaptation, the toolbar ends up being higher than in other
adaptations. These changes in toolbar height propagate to the main
display area and cause the jump. I don't think v5.x did this.
The easy work-around that I found was to undock that adaptive toolbar
and move it to near the bottom of the main display screen. When it is
a floating toolbar it can change size and not affect the size of the
main display area.
