Thanks for reporting this issue.

Unfortunately, this is a complex problem to solve.

At the protocol level, X clients really are being told about 
keypress/release events (i.e. Windows WM_KEYDOWN/WM_KEYUP messages map 
in some way to X11 KeyPress/KeyRelease events)

Now, there is a possible mechanism to tell X clients about characters, 
like the WM_CHAR messages being sent by WinCompose, which is XIM, and 
there was some long-ago work in that area [1], but it's not included in 
current X servers.

In the short term, some sort of feature in WinCompose where it turns 
itself off for specified windows might be easier.
