Attached is a simple reproducer. 6087 1 gouessej 2019-02-01 13:58:23 +0100 Your reproducer is wrong, please look at my example: https://jogamp.org/wiki/index.php/Rudimentary_standalone_example_using_the_fixed_pipeline_by_Julien_Gouesse You shouldn't create the animator inside the GLEventListener and you don't even start your animator, it can't work. 6088 2 801 charles.huet 2019-02-01 15:30:06 +0100 Created attachment 801 Reproducer with correct Animator 6089 3 charles.huet 2019-02-01 15:30:52 +0100 Sorry, I commented it out to check the difference, and forgot to re-enable it before submitting, my bad. I uploaded a new reproducer that creates the Animator in the main, and the problem is still reproduced. 6091 4 charles.huet 2019-03-07 11:26:58 +0100 Hi, is the reproducer up to snuff now ? Can I do anything else to help you reproduce this issue ? 6092 5 gouessej 2019-03-07 12:39:29 +0100 The reproducer seems to be correct now. I've not investigated yet but maybe it can't be fixed within JOGL, especially if the root cause comes from AWT. I assume that the problem doesn't occur when using a pure NEWT GLWindow without AWT. 6109 6 sgothel 2019-03-27 04:51:27 +0100 Confirmed This resize flickering is also visible (more or less) with - com.jogamp.opengl.test.junit.jogl.demos.es2.newt.TestGearsES2NewtCanvasAWT - com.jogamp.opengl.test.junit.jogl.demos.es2.newt.TestGearsES2NEWT Animator doesn't make a difference, nor v-sync. Looks like our delayed off-thread resize operation creates this visual artifact while in process, i.e. the blanking (clear buffer) is dominant. Not sure whether I should spend time on this cosmetic.. 6110 7 sgothel 2019-03-27 04:52:59 +0100 Moving product to Newt, component core. AWT (parent window) detail is unrelated here. 6193 8 sgothel 2019-04-04 16:01:28 +0200 Removing flickering is now a feature. We have to see whether this can be done at all, considering our current delayed resize implementation and for which version. Putting this on 2.5.0 for now. 800 2019-01-30 16:01:44 +0100 2019-01-30 16:01:44 +0100 Reproducer for the flickering NewtTest.java text/x-java 2256 charles.huet
