have you tried another browser? eg the samsung one or you could try Firefox from the playstore. it will be helpful as it will show if it is a chrome problem or system wide
It does seem to be only Stuff, which is a bit weird. I shall try those fixes, but I hesitate to change browsers out of sheer laziness. I like multiple tabs for easy switching...
I just don't understand why it is only on this device that it happens. Gremlins?
