[GRASS-dev] Oddity with GRASS 7.2 RC2 on Fedora 25/Gnome

[Roger Bivand]

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.

Best wishes,

Roger
