I maked some videos from two machine with other operating systems. 1) Old notebook with Lubuntu 18.04:
- booting (0:24 issue is shown): https://youtu.be/5ZfDxHV4A2s - turn off/turn on display (this same issue): https://youtu.be/Dn8WG-O2r10 2) Other machine with Ubuntu 18.04 this have also old Ati Radeon card: - booting (0:14 issue is shown): https://youtu.be/oZ2dCiHHB2Y - turn off/turn on display (this same issue): https://youtu.be/8s0sBYdnKzw You can see that both machines is affected by this same issue but in first machine this issue is most visible. I hope that this help and you can now fix this issue or report it. I think that this issue is for Radeon driver but you maybe have more knowledge about it. Please help me.
