[Qgis-developer] qgis eating one core (Debian testing)?

[Richard Duivenvoorde]

Hi,

I'm on Debian testing, running self compiled QGIS.

Both master and master_2 keep one core at at least 80%, making my fan
blow all day :-(

Anybody else that problem?

This copy of QGIS writes debugging output.

Debug does not show anything

Strace shows:

all the time...


strace QGIS 2.14 shows about the same one, but at least not as much/fast..

poll([{fd=6, events=POLLIN}], 1, -1)    = 1 ([{fd=6, revents=POLLIN}])


If I run Wayland, it does NOT show at all?? (but I have other non QGIS
related problems then...)

Anybody a clue?
