I'm confident about the new test case for this ticket, but the resolution is more invasive than I'd like. (It works, though.)
In short: This introduces a new RenderingHint (in SunHints) to bypass the call in Window to `gg2d.fillRect(0, 0, getWidth(), getHeight());` I left more detailed notes here about the proposed resolution: https://github.com/openjdk/jdk/commit/1991fdac5dbf76ddaf73cc78a9f7c38370c9674c I'm open to suggestions if anyone has a more elegant proposal to prevent the monitor from refreshing too soon? ------------- Commit messages: - 8303950: fixing false negative - 8303950: avoid letting Window.paint(..) call g.fillRect(..) - 8303950: adding failing test to identify problem - Merge pull request #4 from openjdk/master - Merge pull request #3 from openjdk/master - Merge pull request #2 from openjdk/master - Merge pull request #1 from openjdk/master Changes: https://git.openjdk.org/jdk/pull/12993/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=12993&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8303950 Stats: 246 lines in 4 files changed: 241 ins; 0 del; 5 mod Patch: https://git.openjdk.org/jdk/pull/12993.diff Fetch: git fetch https://git.openjdk.org/jdk pull/12993/head:pull/12993 PR: https://git.openjdk.org/jdk/pull/12993
