Transition to the new WoW64 wine and wine-staging
2025-06-16
We are transitioning the wine and wine-staging package to a pure wow64 build. This change removes the dependency on the multilib repository for wine and wine-staging.
The main reason for this is to align with upstream Wine development, which simplifies packaging and the dependency chain.
Potential Issues:
OpenGL Performance: A known limitation of the new WoW64 mode is reduced performance for 32-bit applications that use OpenGL directly
Breaking Changes: Existing 32-bit prefixes need to be recreated
If you are facing issues with 32 bit prefixes, please recreate these and reinstall the application.
As your games are using WINE, then any 32-bit prefixes need to be recreated, in any case; I suspect this could be contributing to the crashing, especially considering only these games are affected.
