[skl] GPU hang in Xorg

For half a year I have been experiencing regular GPU hangs in my arch linux KDE4/Plasma installation on a Lenovo Thinkpad X1 Carbon 4th generation (2016).
It only happens when I am using libreoffice word processing software: While typing text, the computer would spontaneously freeze for 10-20 secs, input is interrupted but I can move the mouse, then a notification appears in the system tray reading "KWin Window Manager Desktop effects were restarted due to graphics reset.", and then I can continue working.
(The notification is similar to this message: https://i.imgur.com/DSgAQBZ.png )
The hang occurs regularly every 2-5 minutes but only while using libreoffice.
Sometimes, about 1 in 10 cases, the mouse pointer freezes as well and the X-Server would crash after 10-20 seconds instead of recovering.
The bug has been persistent through diverse system updates I did during the last half year.
File with GPU error state attached.
Do you need additional information? Thanks a lot.
