Subject: DRI2: synchronize swap interval with server at startup time
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=385e2896ebf54ac0b016132fe513f21a5b67ba4f;p=mesa.git

DRI2: synchronize swap interval with server at startup time

In the direct rendered case, we need to tell the server our initial swap
interval.  If we don't, the local and server values will be out of sync,
since the server and client defaults may be different (as they were
before this patch).
