https://bugs.winehq.org/show_bug.cgi?id=43893 --- Comment #2 from Panard <panard(a)inzenet.org> --- Sure, but in our case, this is to disable only clients in a particular container, not all the clients on the host. Moreover, looking at the current code in winex11.drv/bitblt.c, if the extension is disabled on the server, create_shm_image will still make a lot of work until it gets kicked off by XShmAttach because the current implementation of XShm still enable XShmCreateImage if the extension is disabled ; therefore disabling the extension on the server will lead to very bad performances with wine. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
