discuss 4.15.0-54 the issue quite well, with the associated kernel changes that brought the issues. Since I came across this bug first I thought I would document this for others in the future. I came upon this issue while running a custom kernel 4.19 which did not have the fix for this which I'm assuming were later added to the kernel somewhere between that and 5.1 since running both the default kernel 4.15.0-54 in 18.04 and 5.1.6 did not have this problem while 4.19.57 did.
