Using epiphany-browser via a remote xdmcp session

Epiphany-browser works fine when I am on my physical machine running Xubuntu 22.04, however when remotely accessing the machine via an xdcp connection using vcxsrv I get the following error message:

(WebKitWebProcess:2): Gdk-ERROR **: 17:14:25.307: The program 'WebKitWebProcess' received an X Window System error.
This probably reflects a bug in the program.
The error was 'GLXBadFBConfig'.
  (Details: serial 174 error_code 163 request_code 149 (GLX) minor_code 21)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the GDK_SYNCHRONIZE environment
   variable to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)

(epiphany:115286): epiphany-WARNING **: 17:14:25.386: Web process crashed

I am not sure what this is referring to, unfortunately.

Is vcxsrv configured to use indirect rendering? See for example [Can't run OpenGL on WSL2](https://stackoverflow.com/a/66506098/4440445)

'WebKitWebProcess' is trying to open a connection to an X Window (or equivalent) display manager, pointed to by the `DISPLAY` environment variable. Your `XRDP` connection is not providing this.

@steeldriver thanks for your comment. The `Native opengl` has always been ticked by default for me when using vcxsrv, but I'd never added the environment variable to my `~/.bashrc` file, mainly because I didn't know what it was about. I followed the steps in your provided link, and added: `export LIBGL_ALWAYS_INDIRECT=0` it seems to have done the trick, but will need to test further.

Thanks to the link provided by @steeldriver. I believe the following steps have resolved my issue.

Edit the ~/.bashrc file and add the line: export LIBGL_ALWAYS_INDIRECT=0 to the bottom of the file.

Restarted my machine (a logout would probably be enough).
The opened vcxsrv and made sure the following options were ticked:

Once logged in I was able to epiphany-browser without issue in the vcxsrv session.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
