When I run the following jogl demo it works fine at first. But when I try to resize it the canvas disappears. I just see a blank jpanel in its place. http://jogamp.org/deployment/jogamp-current/jogl-demos/Gears.jnlp The Mac OS X version is 10.9.5 or higher Java 1.8.0_45 It also doesn't work on Yosemite 10.10.3 It is reproducible both with and without Java Webstart. Our standalone application has same problem. This bug was first reported in jogl forum here: http://forum.jogamp.org/Resize-problem-td4034612.html 4818 1 sgothel 2015-07-25 19:17:06 +0200 Test machine - OSX 10.10.4 - Java 1.8.0_51 x64 - Java 1.6.0_65-b14-466.1 x32 and x64 JOGL Unit Tests: - com.jogamp.opengl.test.junit.jogl.demos.es2.awt.TestGearsES2AWT: OK - com.jogamp.opengl.test.junit.jogl.demos.gl2.awt.TestGearsAWT: OK JOGL Demos: - Manual demos.gears.Gears: OK - JNLP Launch reproduces the issue: ERROR <http://jogamp.org/deployment/archive/master/gluegen_868-joal_596-jogl_1401-jocl_1057-signed/jogl-demos/Gears.jnlp> - Error is reproduced if resizing very fast about a bigger amount, e.g. 50% - for the first time! - Error is not reproduced if first resize happen slowly about a tiny amount. Later fast resizes work then. Hence we do have an issue at least on latest OSX w/ latest java8 when running as WebStart - and w/ 'fast resize'. 4828 2 sgothel 2015-07-28 00:36:54 +0200 Root cause: JAWTWindow's JAWTComponentListener 'isShowing' state is initialized while attaching it on-thread and updated via hierarchy-changed event. JAWTComponentListener attachment to the component is issued at JAWTWindow's creation but on the AWT-EDT, hence it may happen at a later time. In this bug scenario, it happens very late, so that the hierarchy-changed event is missed and 'isShowing' is never set to 'true'. Solution is to update 'isShowing' state on the actual AWT-EDT when attaching to the component. Also make 'isShowing' volatile. 4829 3 sgothel 2015-07-28 00:38:34 +0200 commit 4eeddd0d446f8491dde2e5b0e3e11e0d5b0be9b7 Fixed as described in comment 2
