It looks like a condition between calls from `set_visible` to `request_focus`. When `request_focus` is called, the window is not yet mapped (map is requested on `set_visible`).
200x200 is the default gtk window size if none is specified. Since the window is presented at the requested size and then changes to 200x200 I would guess the size request on `gtk_window_present` (which is called on `request_focus`) is being queued and released later. But I'm not really sure. ------------- Commit messages: - FIX for JDK-8316423 - test Changes: https://git.openjdk.org/jfx/pull/1249/files Webrev: https://webrevs.openjdk.org/?repo=jfx&pr=1249&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8316423 Stats: 12 lines in 3 files changed: 10 ins; 0 del; 2 mod Patch: https://git.openjdk.org/jfx/pull/1249.diff Fetch: git fetch https://git.openjdk.org/jfx.git pull/1249/head:pull/1249 PR: https://git.openjdk.org/jfx/pull/1249
