            Bug ID: 51416
           Summary: deferred context memory leak
           Product: Wine
           Version: 6.12
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: directx-d3d
          Assignee: wine-bugs at winehq.org
          Reporter: janbraun at gmx.net

      Distribution: ---

This is a followup to bug#51238. While WoWs now starts and is playable with
deferred contexts, it leaks LOTS of memory.

For comparison, without deferred contexts [either wine < 6.10, or by adding
"return E_OUTOFMEMORY;" at the beginning of *_deferred_context_create() in
current wine], WoWs sits at a fairly constant 8G virt, 2.5G res memory usage
here.

With unmodified wine 6.12, WoWs arrives at these values when it finishes
loading, but then continues to gobble up an additional approx. 1G virt=res per
minute, just for sitting idly in the port UI, backgrounded. Memory usage keeps
rising similarly during actual gameplay, though I haven't measured that in
detail.

Obviously, swapping and general mayhem eventually ensues.
