Hello @peterjc123, you've come across a downstream fork of wine used in Proton. These merge requests look like they should be reviewed and merged into upstream wine (https://gitlab.winehq.org/wine/wine/), and afterwards, if this is needed to fix a game with Proton, you can make a request to backport the accepted commits to Proton's variant of wine.
@kisak-valve Sorry for posting them here. I'll try to get it to upstream wine.
@kisak-valve After a second look, it seems that #230 only works for proton-wine, since the argument flags doesn't appear in upstream wine.
@kisak-valve #231 is similar, since these args flags and uri are only available in proton-wine. That's why those changes are needed in this repo, not the upstream wine.
@kisak-valve And there is another patch, https://github.com/ValveSoftware/wine/pull/233. I've checked that it doesn't apply for upstream wine.
Fixes: #230 #231
