Potential bug in JAVAFX > 12 (GL_FRAMEBUFFER_INCOMPLETE_ATTACHMENT)

    Details

    • Subcomponent:
    • CPU:
      x86_64
    • OS:
      linux_ubuntu

      Description

      ADDITIONAL SYSTEM INFORMATION :
      Ubuntu 20.04 LTS running on a HP Envy 17 laptop.
      Also Ubuntu SNAP base 20 container
      jdk 11 to 15.0.1 all show same error
      OpenJFX 13 to 15 show the same error, OpenJFX 11 and 12 do not display the error and work normally

      A DESCRIPTION OF THE PROBLEM :
      I have built a LINUX based Ubuntu snap app using BASE20 (i.e. Ubuntu 20.04) as a target OS, and it is in distribution through the Ubuntu snap store. The runtime is built using JLink to create a standalone JAVAFX package that is then wrapped into a UBuntu snap with the Base 20 image and a set of libraries for distribution in a totally self-contained snap container.
        
      The App works perfectly well using OpenJDK 11 through to 15.0.1 and on OpenJFX 11 and 12. However if I move to a more recent version of OpenJFX (e.g. 13 through 15) I get the following error for every scene change on my primaryStage following the opening scene which always opens correct. For all following scene changes the screen goes blank and the following error is displayed on the terminal:

      Incomplete attachment. (GL_FRAMEBUFFER_INCOMPLETE_ATTACHMENT)(FBO - 820)
      Error creating framebuffer object with TexID 1)

      One thing - the application does not crash, it continues to run normally with a blank white screen until something forces a screen refresh e.g. manually opening another full screen app, then closing it again - the desired scene then appears when the screen refreshes!

      It fails running within a UBuntu 20 Snap and as a standalone JAVAFX application running on UBUNTO 20.04, and when running within my dev environment:

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      On start up first scene will display normally. Pressing the toolbar button should initiate display of second scene, but a white rectangle will be displayed instead.
      Start another program to fill the screen, then minimise it. The second scene will be displayed as expected. Pressing the cancel button should cause the first scene to be displayed, however a white rectangle will appear. Maximise another application then minimise, and the white rectangle will disappear and the expected scene will be displayed.
      ACTUAL -

              mPrimaryStage.show();
          }
          
      //===
      ```
      The Above Method is called by:
      ```
      //==
      public PhotoCarousel(ImageContainerCallBack imageContainerCallBack, Stage primaryStage, Scene lastScene, UUID photoNotebookUuid, int imageNumber)
          {

      ```
       NOTE setupscene() in the above method is a method that creates the scene, and works fine in JAVAFX 11.0.2 -> 11.0.5
      The Above Method is called by:

      ```
      //===
         private void openPhotoCarouselButtonClickHandler()
          {
              mOpenPhotoCarouselButton.setStyle("-fx-background-color:MediumSeaGreen");

              {

                  PhotoCarousel photoCarousel = new PhotoCarousel(this,
                          mPrimaryStage, mScene, mPhotoNotebookUuid, 0);

              }
              resetButtonColours();
          }
        
      //===
      ```
      the next code fragment is part of a method that creates buttons and places them on a tool bar. the button described in the fragment uses a lambda to set the button setOnAction variable

      The Above Method is called by:

      ```
      //===
           .
           .
           .
              mOpenPhotoCarouselButton = new Button();

              mOpenPhotoCarouselButton.setPrefWidth(buttonWidth);
              mOpenPhotoCarouselButton.setText("Photos");
