Off-topic here sorry. But: MSP 16 has an nvidia GPU, so when the GPU is
stressed, it will automatically switch to the NV GPU, therefore avoiding intel
GPU's overheating problem under Linux. I have been testing a few workarounds
and they seems to work by suppressing CPU package's power cap. I will do some
more research and report the the issue to where it should be.

# About the applet:

The applet is xsensors. Its only function is to show the hardware's
temperature. It has nothing to do with Krita what so ever. It has 4 tabs inside
its interface. That it. It doesn't even have a menu.


# Pressing Ignore:

I did press Ignore, but new INTERNAL ERROR messagebox just kept popping up. It
was in an constant INTERNAL ERROR loop. Only Abort stopped the madness.


# P.S. Krita's OpenGL stress

I'm using xsensors to investigate my Wacom MSP13 (and other laptops) keeps hard
resetting themselves under Linux. I think it is an Intel integrated graphics
specific problem because there is no GPU thermal sensor being provided under
Linux. The GPU part turbo boosts under stress, overheats itself until it shuts
down by hardware safety measures. 

A peculiar finding: Krita is very good at making the GPU overheating, too good. 

I was trying this seemingly demanding WebGL2 demo:
https://playcanv.as/e/p/44MRmJRU/ which on MSP13 it couldn't even run past 10
FPS under Ultra setting. However, the CPU package temperature rarely went over
60C. 

On the other hand, a few simple dabs in Krita and it immediately shoots all the
way over 70C. If I combine drawing with rotation, panning, zooming, picking
color...all these OpenGL actions, MSP13 just kills itself very soon after.

Keep in mind this is not only happening on MSP13, but also a number of
different laptops I tried Krita on them.

Any insight about what is happening here? Anything more I can do to investigate
to help, or I should report this as another bug?

It is related to the experimental option to use Qt's xcb implementation,
instead of our fork. Our fork breaks scrollwheel input with current versions of
X11; Qt's seems to send events in a weird order and can break switching focus
and when moving from the dockers to the canvas. 

This is the full backtrace:
