Subject: [winswitch] Trouble using Xpra with Xquartz
Message-ID: <ypvilif6ito.fsf@shell02.i-did-not-set--mail-host-address--so-tickle-me>

[fourth attempt]

I'm running into a problem using Xpra with Xquartz (the X11 server for
MacOS).  Specifically, I can't get the "xpra attach" command to start
the client.

To reproduce:

    $ xpra attach ssh:foo.example.com:20

    $

xpra pops up a status window which gets to this point before crashing:

    Xpra Client v4.4.3
    - initializing
    - validating OpenGL: success (Intel(R) HD Graphics 6000)
    O client configuration

The host foo.example.com doesn't exist, of course, but using that name
demonstrates that the problem is independent of the state of the xpra
server.  (Using a host name that has an xpra server doesn't change the
result, nor does adding "--ssh=ssh" to use /usr/bin/ssh for connecting.)

The environment is:

    x86 MacBook
    MacOS 12.6.1 (Monterey)
    XQuartz-2.8.2
    xpra v4.4.3-r1

Has anyone been successful using Xpra with Xquartz?

Hi,

xpra-html5 version 6.2 is now available:
https://github.com/Xpra-org/xpra-html5/releases/tag/v6.2
This version fixes flickering issues with some versions of Firefox and 
other problems introduced by the new offscreen paint decoder.

Cheers

This specific bug is discussed here:
https://github.com/Xpra-org/xpra/issues/3701#issuecomment-1345268873
And will be fixed in the next release.
There is a workaround in the github issue above.
(older versions are not affected by this particular issue - though I am 
not certain which ones)

 > Has anyone been successful using Xpra with Xquartz?
FYI: xpra does not use XQuartz at all.
Having it installed - or not, should make no difference.

Cheers,
Antoine
