Side note: you can find a bunch of runs with these failures there: https://testbot.winehq.org/FailureDetails.pl?Key=296
Reporting successful reproduction: * Identical symptom: unexpectedly empty update region, as reported by test_swp_paint_regions() * Identical platform version: Windows 7 (w7*). * Identical observation of relevant environment state: desktop creation and switching was successful, so firewall alert dialogs are unrelated. Further actions: - Capture the screenshot at the exact point in time when the relevant failure has happened. - Test hypothesis 1: the window was obscured by another window. - Test hypothesis 2: the window was created hidden or minimized. - Test hypothesis 3: a Windows API call failed, but its error status is not being checked or flagged. - Test hypothesis 4: transient failure of environment or interference from other USER-related programs. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
