Jeremy Wood has updated the pull request with a new target base due to a merge
or a rebase. The incremental webrev excludes the unrelated changes brought in
by the merge/rebase. The pull request contains five additional commits since
the last revision:
- 8382201: adding extra {}'s for code review
- 8382201: resetting RepaintManager so diff is clean
- 8382201: removing isWrongOpacity
Also simplifying unit test so it doesn't require a white background Frame.
The opacity issue is important, but it can be represented as a separate
ticket. (I'm trying to keep PRs as simple as possible to speed up/simplify code
review.)
- Merge branch 'master' into 8382201
- 8382201: createAcceleratedImage returns translucent window if needed
Also RepaintManager may let windows share the same buffer. In this test's
case: the white background (in an opaque Frame) set up a large buffer, and the
smaller translucent dialog needs to recreate a buffer to provide translucency.
