[Bug 53277] New: user32:edit - The edit field is sometimes empty after a paste on Windows
https://bugs.winehq.org/show_bug.cgi?id=53277 Bug ID: 53277 Summary: user32:edit - The edit field is sometimes empty after a paste on Windows Product: Wine Version: unspecified Hardware: x86-64 OS: Windows Status: NEW Severity: normal Priority: P2 Component: user32 Assignee: wine-bugs(a)winehq.org Reporter: fgouget(a)codeweavers.com user32:edit - The edit field is sometimes empty after a paste on Windows: edit.c:3211: Test failed: got 0 edit.c:3240: Test failed: got 0 https://test.winehq.org/data/patterns.html#user32:edit These two failures can happen independently. This may be caused by clipboard interference (see bug 47888 and bug 53276), though such interference is supposed to preserve the content of the clipboard. Furthermore this not only happens with the Radeon driver but also on plain QXL VMs (w1064-1qxl on 2022-05-06 and 2022-05-31) and Nvidia machines (cw-gtx560 2022-04-26). So this is probably related to the above bugs but it looks as if the clipboard gets cleared after it has been set which means a different workaround would be required (e.g. retrying the whole Copy+Paste multiple times). -- Do not reply to this email, post in Bugzilla using the above URL to reply.

But resending a WM_PASTE a while after just pastes the expected content -- Do not reply to this email, post in Bugzilla using the above URL to reply.
