Babaschess is using around 20% CPU1 and 20% CPU2 of my dual core E2100 once opened, without doing nothing. On Windows you can see that the program only uses around 0-1% CPU.
What is really strange is that when you open the preferences dialog the CPU drops to 2-3%, a much nicer behavior like in windows.
There is something clearly wrong because the CPU utilization is excessive, when the program is doing nothing, no animations, no game analisis...
I guess that maybe wine is re-drawing constantly some of the sub-windows when there is no necessity to redrawn...
This is not a regression I have always observed this behaviour on this program.
I've tested with 1.5.29 and I indeed get more CPU usage (8% on a core) on idle than when opening preferences (0-2%). Don't know if that's significant, though.
FWIW, the log only contains lines like fixme:wincodecs:PngDecoder_Block_GetCount 0x23c7730,0x33e918: stub
Can you please retry (with preferably an old CPU) to see if the problem still occurs for you?
