Hello all:

I've build kicad several times and I've noticed that if I do a debug 
build -DCMAKE_BUILD_TYPE=Debug, then eeschema or pcbnew works but uses lots 
of cpu time. I got some backtraces, build for svn r983

Another one a little later:

Following this trace, I found that the loop occurred at IA__g_main_loop_run.

I haven't programmed on WxWidgets or gtk and I don't know if this behaviour 
is expected. I find strange taking full cpu permanently even when using the 
Debug build for no apparent reason.

I'd appreciate some clarification.

Best regards,
