steam-702890.log

Additional Information

This may relate to Blazblue Central Fiction (586140) too as the same render error was posted there.
4.2 error:
fixme:d3d9:d3d9_device_CreateRenderTargetEx stub!

Progress

4.2 error was patched in 4.11-1. This was merged into Proton 4.11-1 as 2b3955e

Using protonfixes with a winetrick for quartz removes one of the errors in the log.

The game runs. The offline modes and multiplayer lobby seems to work (regardless of quartz). Game occasionally crashes when listing multiplayer lobbies (especially if done quickly).

Start by reproducing the multiplayer lobby crash with Proton 4.11-1 and compare steam-702890-updated.log with the working steam-702890.log. Use the linked system information and logs to identify the difference associated with rapid lobby listing; done means the game no longer crashes in that scenario.
