Great, thanks.

The zip file available on the download page, which contains 
Xpra-Python3-x86_64_4.0.1-r26379. zip md5sum:

Yes, I uploaded screenshots to https://imgur.com/a/eD4NltE . The left 
dialog appears first and the right one immediately afterward.

There are several other copies of libintl-8.dll on my system, since a 
lot of open source software ships it. One of those might be getting 
picked up from PATH instead of the one in lib. Xpra.exe, 
Xpra-Launcher.exe and Xpra_cmd.exe all fail. After copying the dll from 
lib one level up, everything works.

Is there any other way to _not_ have Xpra do keysym-based mapping though?

Use case: I use a heavily customized multilingual layout on Windows. 
When connecting to X11 boxen, I generally only need standard US layout. 
I would prefer that keys are mapped using the server-side Xkb layout 
starting from keycodes (as happens with VNC, NoMachine and such) to 
avoid funkiness.

Example of a problem: the [ key (scancode 0x1a) produces ä (adiaeresis) 
with my Windows layout. When I connect with Xpra, it sets Xkb layout 
"us" on the remote (my Windows layout has locale US so this is an 
acceptable guess). When I press the [ key, nothing happens because (as 
far as I can tell) Xpra server side doesn't know what to do with the 
keysym adiaeresis since it doesn't appear in the Xkb us layout. What 
would preferably happen is that the scancode/keycode gets passed to X as 
usual and eventually pops up as [.
