in the last 4 updates on Grimson relive/vulkan, i have encountered some annoying behavior when , using display port and using 4k screen.
all the time when using browser or software, it somehow restart connection to display port.
I reinstalled several times but no luck.
Now i narrowed it down to that it somehow connected to the scaling option in win10 where you can scale desktop upto 350 %
when using no scale 100% there is no flicker or restart of the connection, but on every other scale options there is when hell begins.
here you see how it restarts or looses the connection
