When I use LibreOffice Writer, after a few minutes, the whole GUI freezes (except the mouse that continues to move but click is inoperative) and X restarts.
The relevant diagnostic from dmesg is:
[drm] GPU HANG: ecode 9:0:0x85dffffb, in Xorg , reason: Hang on render ring, action: reset

Open LO Writer, type some text, scroll page, change window...
After a few minutes, everything freezes, not only LO.

Forgot to mention that I have hybrid graphics.
The discrete GPU is [AMD/ATI] Venus XTX [Radeon HD 8890M / R9 M275X/M375X] (rev 83).
