The issue was with the view's position, specifically the content's X and Y coordinates relative to the window, including its decorations. When in fullscreen mode, the window remains decorated, but the decorations are hidden. As a result, the content's position needs to be recalculated to account for the window's adjusted layout.
It's not specific to i3. I used `gdk_window_get_root_origin` because GTK will try harder to find the value, even if `_NET_FRAME_EXTENTS` is not supported on some Window Manager. ------------- Commit messages: - Forgot debug print - 8348095: [Linux] Menu shows up in wrong position when using i3 windows manager in full screen mode Changes: https://git.openjdk.org/jfx/pull/1702/files Webrev: https://webrevs.openjdk.org/?repo=jfx&pr=1702&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8348095 Stats: 19 lines in 3 files changed: 3 ins; 1 del; 15 mod Patch: https://git.openjdk.org/jfx/pull/1702.diff Fetch: git fetch https://git.openjdk.org/jfx.git pull/1702/head:pull/1702 PR: https://git.openjdk.org/jfx/pull/1702
