I was adding some text nodes (com.jme.scene.Text) to the fpsNode for debugging purposes and I had a problem.
When my camera is focused against a texture that had the UV coords changed, some black pixels appears on the font borders.
Btw, the node used for the HUD is the fpsNode from BaseSimpleGame, then I attached the Text node(s).

Did anyone see something like this? Is the problem in JME or in my application? Maybe a missing updateRender…() ?
