It's not the size of View, it's the preferredSize that is wrong. This
is because tip's GC is null before the tip is shown, so View's span
is calculated accordingly. Only when View isupdated when
"graphicsConfiguration" is fired, then Tooltip GC is updated and
preferredSpan is calculated correctly.
It's to be remembered that the issue happens only when html text is
shown in ToolTip. If normal text is shown , there is no issue. I
guess if it's a question of wrong GC during popup reset/pack, then it
will cause problem during normal text rendering also, no?
If GC of the tip is null before showing then can we use default screen
GC by default? Same as in the java.awt.Window.initGC().
I tried but SwingUtilities.windowForComponent(tip) returns null so there
is no "Window" parent associated with tooltip so initGC() cannot be
called on tip, as I see.
Also, tip GC is null for normal text too, where it works. Only
difference between normal and html text is in calculation of
getPreferredSize/MaximumSize/MinimumSize where the size is updated based
on updated span calculation, so I have used updated preferredSize in my fix.
