This series tries to fix WM_PASTE tests error on edit control (both user32 & comctl32). The test failures where systematic on a local Win10 for comctl32 (yet very rare on user32, perhaps one in 20 runs). Since the failures are not systematic, it ought to be a synchronisation / timing issue. Flushing the msg queue before starting the paste test cycle seems to fix the issue. - 0 occurence on comctl32 and user32 in 50 run (local VM) - 0 occurence on Testbot (comctl32) in 1 run. It's hard to be fully conclusive about bug resolution, but it's at least a step into the right direction. -- v2: comctl32/tests: Fix failing WM_PASTE tests for edit control on Win10+. user32/tests: Fix failing WM_PASTE tests for edit control on Win10+. https://gitlab.winehq.org/wine/wine/-/merge_requests/1886
