[PATCH v7 0/3] MR231: Draft: SetWindowPos() parent window exposure fixes (#53153)
Signed-off-by: Jinoh Kang <jinoh.kang.kr(a)gmail.com> -- v7: server: Don't invalidate the newly exposed child region on the parent if it doesn't clip children. server: Redraw composited window child when its z-order changes. server: Correctly expose composited parent window and its child on position change. https://gitlab.winehq.org/wine/wine/-/merge_requests/231
From: Jinoh Kang <jinoh.kang.kr(a)gmail.com> Skip redrawing the composited child window when the window rect and visible region stays the same, since we're taking the union of the old and new visible regions.

Hi, It looks like your patch introduced the new failures shown below. Please investigate and fix them before resubmitting your patch. If they are not new, fixing them anyway would help a lot. Otherwise please ask for the known failures list to be updated. The tests also ran into some preexisting test failures. If you know how to fix them that would be helpful. See the TestBot job for the details: The full results can be found at: https://testbot.winehq.org/JobDetails.pl?Key=125569 Your paranoid android. === debian11 (32 bit report) === comctl32: edit.c:3453: Test succeeded inside todo block: Set focus: marked "todo_wine" but succeeds
