Yes it is probably the same bug. It's a right-most vertical interlaced line.
I'm currently experiencing this bug in the newest ubuntu mainline kernel
(4.19-rc5). [It's not an issue on 4.18.8 kernel] I'm relatively inexperienced,
Applying kernel patches seems a little difficult for me. I only know how to
install mainline kernels from ukuu or .deb files. I can try if someone links me
clear instructions. Thank You for Your time and help. I hope this will be fixed
in future Linux kernel versions.
