<pre>Hello Michael,
First to all could you attach a dmesg log with debug information, drm.debug=0xe
on grub, as mentioned here:
<a href="https://01.org/linuxgraphics/documentation/how-report-bugs">https://01.org/linuxgraphics/documentation/how-report-bugs</a>
You mentioned you updated to 4.14, are you using any firmware?
<a href="https://01.org/linuxgraphics/downloads/firmware">https://01.org/linuxgraphics/downloads/firmware</a>
so, are you facing also a corruption issue with the display scaled only with
KDE? Have you tried another desk like gnome?
Thank you.</pre>
