errael opened a new pull request #2482:
URL: https://github.com/apache/netbeans/pull/2482
In ide/editor/lib/BaseCaret there's
```
newCaretBounds = c.getUI().modelToView(
c, offset, Position.Bias.Forward);
// [TODO] Temporary fix - impl should remember real bounds computed by
paintCustomCaret()
if (newCaretBounds != null) {
newCaretBounds.width = Math.max(newCaretBounds.width, 2);
}
```
When offset is sitting on a TAB character,
editor.lib2's TabView's `modelToViewChecked(int offset, Shape alloc,...` does
```
mutableBounds.width = 1;
return mutableBounds;
```
So the min of 2 applies and the caret drawing code gets a graphics context
with clip width of 2.
This causes a drawing problem for the caret which can be ovserved in
NetBeans. The problem may be exacerbated for plugins that provide their own
caret. This fix provides a workaround that can be used by plugins until (if)
the problem is addressed.
