On macOS the system animates the transition into and out of fullscreen and this animation runs asynchronously. JavaFX tries to make the setFullScreen call appear synchronous by running a nested event loop while the transition is going on. But this means that runLater runnables can fire during a call to setFullScreen.
This can also occur during a call to Window.hide() if the window is in fullscreen mode. During the setView call glass tries to take the window out of fullscreen mode which fires up a nested event loop and, again, runLater runnables (like pulses) start firing. In this PR GlassRunnables that try to run during the fullscreen transition are instead placed in a deferral list. When the fullscreen event loop exits they are re-scheduled. ------------- Commit messages: - runLater runnables deferred while fullscreen nested event loop is running Changes: https://git.openjdk.org/jfx/pull/1797/files Webrev: https://webrevs.openjdk.org/?repo=jfx&pr=1797&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8176813 Stats: 31 lines in 3 files changed: 25 ins; 4 del; 2 mod Patch: https://git.openjdk.org/jfx/pull/1797.diff Fetch: git fetch https://git.openjdk.org/jfx.git pull/1797/head:pull/1797 PR: https://git.openjdk.org/jfx/pull/1797
