[peepo]

see attached file:
OpenCL_error_KataGo_engine_died.txt

Katrain 1.15.0 with included KataGo executable
installed and updated with pipx
Ubuntu 24.04 up to date
Late 2018 Intel Macmini

I have been using Katrain on this box since late 2020 mostly to review 9x9 games, I do not recall previous instance.
Game had been reviewed, and left open, with display off, overnight.

closed Katrain, then run again, as per attachment, seems fine.

if there is a log or other info, let me know.
