Hmmm. No.
I can't reproduce the problem. Please attach the file.
Please specify the exact versions used at both ends, as well as the distro version.

Server: Xenial / r25174, Client: Win10 / r25468
Screenshot is not really needed. If I do:
a = b'\x89PNG\r\n\x1a\n\x00\x00\x00\rIHDR....' with open('Screenshot.png', 'wb') as f: f.write(a)
It will save the screenshot as expected (It will take some time to paste 450kb chars in the terminal, but it will happen).

I cannot reproduce any problems.
Tested with 3.0.6-r25174 on a Xenial server and win10 client as well as xenial client.
Tested with python2 and python3 versions of the client and server.
You must have left some important detail out. For a start, the python version(s) used and the exact command lines.

Then, to "render" the image (included in the attachment):
Simply prepend SCREEN =
to the file and then:
In [1]: exec(open('Screenshot.png.txt').read()) In [2]: with open('Screenshot.png', 'wb') as f: ...: f.write(SCREEN) ...:
Also also, while checking (in the server) that the file is "rendered" correctly:
$ xdg-open Screenshot.png xdg-open: failed to forward to xpra server using socket '/run/user/1000/xpra/usr-2': write() argument must be str, not bytes
And the image opened remotely

And... the bit I was missing is that you're using the bug report tool with python3 and not the xpra screenshot
command.

I think I know where the problem is.
The usual strings vs bytes python nonsense.
