Just got a MNT Reform classic yesterday and while using it I noticed some strange screen glitches: flashes of horizontal lines, either white or different colors. Here’s a video I took of that.
Today I noticed a different type of glitch (although on reflection this second one may be an unrelated software issue, I’m not totally sure). But I’m still seeing the other type of glitches as well.
In both cases the glitches don’t happen when the laptop is first turned on, but seem to start after about 5-10 minutes of use. I noticed that the CPU temperature was 40-50 degrees, and they happened both when the CPU was under load and not under load.
My first theory was that maybe the display cable was pinched but two things seemed to rule that out:
- Moving the hinge doesn’t cause the glitches to change, increase in frequency, or go away.
- When I looked at the cable it did not appear pinched in any way (though it was a bit flattened looking).
My current thinking is that maybe this is heat-related, since that might explain why it doesn’t happen when the laptop is cold, just after starting.
I tried running GPU programs (e.g. glxgears) and playing Youtube videos. Neither seemed to make the problem worse or different.
Has anyone else seen something like this? Anyone have any suggestions for what else to look at or possible solutions?
