with this patch applied:

--- a/dlls/winex11.drv/opengl.c
+++ b/dlls/winex11.drv/opengl.c
@@ -2053,7 +2053,8 @@ static void WINAPI X11DRV_wglFlush(void)
     sync_context(ctx);
     pglFlush();
     wine_tsx11_unlock();
-    ExtEscape(ctx->hdc, X11DRV_ESCAPE, sizeof(code), (LPSTR)&code, 0, NULL );
+    if (ctx)
+      ExtEscape(ctx->hdc, X11DRV_ESCAPE, sizeof(code), (LPSTR)&code, 0, NULL
);
 }

tracked runs fine. you seem to believe the context should be set but in this
