Description: Don't know if it should report separately. I indirectly reported it already on MacOS (bug 103571 and bug 99784), but it issue also exists on Windows Steps to Reproduce: 1.Download and install Cygwin 2.Run in Cygwin: SAL_LOG=+INFO+WARN+RELATIVETIMER '/cygdrive/c/Program Files (x86)/LibreOfficeDev 5/program/swriter.exe' 3.Move the mouse over the blank document Actual Results: SAL_LOG is flooded with DoYield; Leave ImplYield, Enter ImplYield and only moving around the mouse uses 2% CPU power Expected Results: I suppose it shouldn't be happening Reproducible: Always User Profile Reset: No Additional Info: Version: 5.4.0.0.alpha0+ Build ID: d538d3d84172a74dfe97d59a6d3daf9a45459cab CPU Threads: 4; OS Version: Windows 6.19; UI Render: default; TinderBox: Win-x86@39, Branch:master, Time: 2016-12-14_00:28:59 Locale: nl-NL (nl_NL); Calc: CL User-Agent: Mozilla/5.0 (Windows NT 6.2; WOW64; rv:45.0) Gecko/20100101 Firefox/45.0

Absolutely expected. Don't enable the logging if you don't know what you are doing. Especially enabling +INFO without limiting to a subset causes huge amounts of log messages. Keep in mind that the whole SAL_LOG feature is only available in developer builds and is used for debugging.
