You can try installing corefonts with winetricks:
WINEPREFIX=/home/doug/Storage/SteamLibrary/steamapps/compatdata/559100/pfx/ winetricks coreconts
(just replace the path & appid)
I've made an issue about winetricks stuff over here #54 perhaps corefonts should be installed by default too?
Thanks @DougTy that worked perfectly and now tooltips are showing up. For anyone new to linux who comes across this, you can get the app id by visiting the steam store URL. The full command for this particular app is:
WINEPREFIX=/home/<username>/.local/share/Steam/steamapps/compatdata/227320/pfx winetricks corefonts
Replace <username> with your user account.
Hi @BlakeHepner,
Because the Corefonts wineprefix workaround was successful for you:
It's a good time to re-test YNAB4 with a clean install, because there are now Corefonts included with the 3.16-4 Beta version of Proton:
Proton now ships with corefonts support. This should fix many games with missing text, or that crash due to missing font support.
So YNAB 4 might now work and look right, out of the box.
For YNAB4, there is as far as I can tell, only a single issue with it. Tooltips are not displaying properly. On a traditional wine setup, this is fixed via installing winetricks and then using that to install corefonts. I am not sure how to do this on proton, but even though you can no longer purchase YNAB4 through steam, this same fix would likely apply to many other games with font rendering issues as the corefonts dependency is pretty common.
