[Possible Linux/Proton-specific Issue] Map marker placement does not match mouse click location

[runic finch]

Want to say this may be specific to my setup (I fully accept the consequences of playing on Linux, etc) but under latest Proton or Unreal Linux native (tested both), there's a map marker placement bug.
Attempting to place a map marker under the mouse position with right-click on the map screen and confirming the map marker does not place the marker under the cursor, and instead places the marker in the top-left corner (I assume screen space origin x:0,y:0)

Images show issue:

1. Attempting to place marker at current player pos
2. Confirming on the map screen
3. Where the marker is actually placed, viewable after zooming out

It may be an environment/system-specific issue, so I have no expectation of support. Saw that Windrose doesn't have an issue tracker yet on the Proton github. I can send this there for better troubleshooting if needed, especially if this isn't being seen on Windows machines.

Thanks again for your time. Game is very fun.

Thanks for the report! You're right, this doesn't seem like a highest tier bugfix priority right now, but we'll look into it when we can.
Can you provide your game logs? They are usually in userlocaldata/R5/Saved/Logs

Maybe we can figure out what goes wrong.

Getting logs now. @signal drum

So, funny story, got the logs, attached them, and then decided to do two things: 1) drop Proton to 9.0-4 (from Proton's experimental branch) and 2) change the window from borderless to fullscreen. After seeing the issue was resolved, I further deduced that the Proton version change only was the solution. Interstingly, on 9.0-4, menu buttons are unclickable until alt-tabbing, but this may be a Proton-exclusive window focus issue specifically with my env (X11/KDE6).

tldr (for anyone that has similar issue): If using Proton, change Proton version to latest (for me at time of post, this was 9.0-4) rather than Experiemental or Hotfix. If buttons can't be clicked, try alt-tabbing.
I'd consider this resolved. Ty for your time. @signal drum
