Title: [regression] Mir is holding buffers much longer than it used to. Status in Mir: Fix Released Status in mir package in Ubuntu: Fix Released Bug description: Mir is holding buffers much longer than it used to. You can see from this bespoke logging that it's now holding each buffer from the client for a full frame even though the compositor itself only holds it for less than a millisecond (the render time): [1438332770.923332] mirserver: 0x7f66bc0030b0: compositor acquired 0x7f66bc0039f0 [1438332770.923444] mirserver: 0x7f66bc0030b0: compositor release1 0x7f66bc0039f0 [1438332770.923454] mirserver: 0x7f66bc0030b0: compositor release2 0x7f66bc0039f0 [1438332770.939927] mirserver: 0x7f66bc0030b0: compositor release3 0x7f66bc0039f0 [1438332770.939966] mirserver: 0x7f66bc0030b0: compositor release4 0x7f66bc0039f0 [1438332770.940011] mirserver: 0x7f66bc0030b0: compositor acquired 0x7f66bc006990 [1438332770.940117] mirserver: 0x7f66bc0030b0: compositor release1 0x7f66bc006990 [1438332770.940127] mirserver: 0x7f66bc0030b0: compositor release2 0x7f66bc006990 [1438332770.956487] mirserver: 0x7f66bc0030b0: compositor release3 0x7f66bc006990 [1438332770.956507] mirserver: 0x7f66bc0030b0: compositor release4 0x7f66bc006990 The issue appears to have been introduced in: ------------------------------------------------------------ revno: 2323 [merge] author: Daniel van Vugt <daniel.van.v...@canonical.com> committer: Tarmac branch nick: development-branch timestamp: Tue 2015-02-17 08:19:29 +0000 message: Fix the multi-monitor frame sync logic to support high speed compositors (tm) which only need to hold buffers very briefly (introduced in r2183). (LP: #1420678) Both the multi-monitor frame sync logic and the optimization of r2183 behave correctly independently. It's only when combined that they start to interfere with each other. But we'd very much like to keep both. Fixes: https://bugs.launchpad.net/bugs/1420678.
