Hi Peppe, Ede and the other developers, I've tested on a Ubuntu 11.10 with OpenJDK and get the same problem. In summary I can say, that on all tested systems the problem exists :-( It did no matter what desktop (KDE, Gnome, Unity) or what JRE (Sun Java 1.6/1.7 or OpenJDK) you are using. In the last two weeks I've researched for a reason, because i now other Java software on linux with XOR painting that haven't any problem.
With a small testclass for a rectangle movement with xor painting there are no problems. But with only a LayerViewPanel in a JFrame without all the other OJ stuff such as menus, toolbars etc., i got the problem. Next I've debugged the computation of the coordinates and size of the Shape during painting, but no success. Than on my old home desktop with debian lenny and a nvidia graphics i got success with enabled OpenGL rendering (-Dsun.java2d.opengl=True)???. On all other linux boxes the opengl rendering on linux seems to be very buggy, because not even the GUI was correct painted. And yesterday i found randomly the reason :-) In the AbstractCursorTool.getGraphics2D() which is called before every painting the RenderingHint for antialaising is set to ON. If i do not set this, every thing works fine :-) Small detail, big difference! Tested with my small testclass and antialaising switched on i cannot reproduce the problem. So i suspect, that this behaviour especially depends on other deeper rendering things in OJ. In principle i mean that this is a special Linux JVM problem and i hope that this will be fixed in the future. So it makes at the moment no more sense for me to deeper search. Finally I've commited a small workaround/fix. On linux platforms we don't switch on antialiasing. But only during paint operation of the Shape!!! This concerns no other paintings.
