If nothing looks more promising, try a different display. I have
experienced a problem that resembles yours when I tried to use a modern

(without 4K capability) works. I have not tried my high resolution
display recently, but will conduct an experiment with up-to-date F26
software if there is any interest.
That's completely unrelated and the screen in that instance goes black.
I do not know whether this display sensitivity was present with F25

other problems made it necessary for me to blacklist VC4 for F25 (and
pre-release F26.)
It was worse in F-25
