It appears this bug when unnoticed in the 0.25.0 and 0.26.0 releases because our major toolkits all use GL and not software surfaces. So almost all our apps won't ever hit the bug.
Xmir also uses hardware surfaces on desktop so won't hit it. We would have noticed the bug in Xmir on Android where it uses software mode, but our Android platforms (OTA-14/15) are all still running Mir 0.24.0 where this bug does not occur. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/1663062 Title: [regression] Software clients of nested servers are all black in Mir 0.25.0 and later Status in Mir: Triaged Status in Mir 0.25 series: Won't Fix Status in Mir 0.26 series: Fix Committed Status in mesa package in Ubuntu: Invalid Bug description: GPU apps seem to work.
