[Bug 43009] TIM message manager window covered by an unresponsive window

https://bugs.winehq.org/show_bug.cgi?id=43009

--- Comment #23 from Dmitry Timoshkov  ---
It should be possible to verify my guess by disabling the shaping of
layered windows on winex11.drv side. In order to do that create a key
"ShapeLayeredWindows"="N" under "X11 Driver" section in the registry.
See https://wiki.winehq.org/Useful_Registry_Keys how to do it, it looks
like ShapeLayeredWindows setting is not documented there.
