With both Wayland and Xorg on the Gnome desktop, displaying elevation @ nc_basic leads to high CPU usage and temperatures > 90C (also -text). This is on a fully updated laptop (Fedora 25 Workstation), GRASS 7.2RC2 built from source. A typical message under Wayland was:
(wxgui.py:27009): Gdk-WARNING **: gdkcursor-wayland.c:170: Unable to load sizing from the cursor theme
(there were others), but I don't know whether the issue is F25, Gnome, Wayland, python, or wxgui. The high CPU usage is python. Of course, it could be hardware, but I typically only see very high temperatures when computing continuously on both cores. Here nothing else (possibly except net polling) was being done, and the temperature was hitting the roof (on a flight, so not funny).
For now, I have to avoid using the display.
This is probably idiosyncratic, but maybe someone else notices something similar.

tested on a 64bit winGRASS7.2 RC2 and on a self compiled GRASS7.2 RC2 on an
uptodate debian jessie 64bit; I can't reproduce it here.

Testing on an F25 desktop does not indicate any CPU overload, on an F25 laptop the problem is present. On the desktop system Python is 2.7.12-7, wxPython is 3.0.2.0-11. On the laptop, the same. So there are hardware and driver differences, I'll continue to look.
