Ernie Rael commented on NETBEANS-4940:
--------------------------------------
One possible solution is to add this method to BaseCaret
{code}
protected void adjustCaretBounds(Rectangle bounds, int offset) {
bounds.width = Math.max(bounds.width, 2);
}
{code}
which is called from udpateCaretBounds.

In a BaseCaret subclass, an experiment to draw a circle around the caret
position worked by overriding the above method with a suitable algorithm.

> Project: NetBeans
> Issue Type: Bug
> Components: editor - Other
> Affects Versions: 12.1

> Priority: Minor

> To recreate.
> # Open a file in the editor (emptyfile, java file,...)
> # Insert a tab into the file
> # Place the caret over the tab
> Observe the caret as it blinks and notice that it only partially blanks.
> There is a vertical artifact.
> The jVi application uses a block caret (rather than a vertical line) and the
> problem is more more pronounced.
