I've searched the Knowledge base for answers regarding this problem and I've re-installed my graphics driver which had no effect. Since installing SO5A whenever it starts the entire display begins to darken and then flicker dark and light. After closing the program the flickering stops but the screen remains dark. It restores to normal after a restart.
I have a Lenovo Yoga 710 running Intel HD Graphics 620 adapter. Intel I7 processor.
Very disappointed to see the number of unsolved display issues over the years on this site.
If you can help, that would be much appreciated. Until there's a fix, I'm looking for other applications that will do the job.
