--- Comment #30 from Chiitoo chiitoo@gentoo.org --- While chasing the leak affecting debug builds [1], I noticed something very similar to this one when running with 'WINE_D3D_CONFIG=csmt=0'.
Pretty much every time I go from the launcher (PlayOnline Viewer) to the game, or from the character selection to and from the game, there is a split second flash of garbage graphics, sometimes parts of a video playing on another screen for example, and the VIRT size jumps up by about 20MB, which was also mentioned here in comment 15.
Eventually the game will crash in 'wined3d' with
err:d3d:wined3d_context_gl_create_wgl_ctx Failed to create a WGL context.
but due to the leak with '-g' or '-O0' optimisations I haven't been able to get a stack with symbols out of that one yet, though it does seem like another(?) leak.
Sometimes there is no proper Wine crash, but just an X11 error instead and the application is terminated with it.
