Already implemented performance boosters : – Get compatible image of GraphicsConfiguration to draw on – Enable OpenGL pipeline in 1.5: Not possible due to severe artifacts

So far I am fine, the main profiled bottleneck of the program is drawing an image with several thousand tiles. Unfortunately it is not regular, else I simply could set pixels and scale them. I accerelated the image with VolatileImages and own rendering routines (ignore repaint and draw it itself with a timer). The result was pleasing and would suffice, BUT: Choosing a JMenu which hovers normally over the part of the image is severely disturbed because the JMenu is overdrawn. Inacceptable and the layout couldn’t be changed.

I tried the GLJPanel of JOGL, but there is no visible performance improvement. So is there a possibitlity to use VolatileImages (or other accerelated lightweighted components like GLCanvas) and still get normal JMenu display and if yes, how ?

  1. You could try to set the popups to non-leightweight. I am not quite sure if it works but it could, because the popup is a native component then and will not be overdrawn. Setting Popups to heavyweight: JPopupMenu.setDefaultLightWeightPopupEnabled(false)
