Bug

Description

Sometimes I use 2/3 monitors for my Hyprland machine and change the input for the other monitor to use with another machine.

triple-monitor config:

monitor=HDMI-A-1,1920x1080@60,-1080x0,1,transform,1 # left 1080 vertical
monitor=DP-3,3840x2160@59.99700,0x0,1 # left 4k
monitor=DP-2,3840x2160@59.99700,3840x0,1 # right 4k

dual-monitor config:

monitor=HDMI-A-1,1920x1080@60,-1080x0,1,transform,1 # left 1080 vertical
monitor=DP-3,3840x2160@59.99700,0x0,1 # left 4k
monitor=DP-2,disable # right 4k

When I switch to the dual config, I get these white/static flashes on my vertical 1080 monitor (HDMI-A-1).

When everything is idling, the issue is rare. When I am actively using the machine or playing a video, the bars are frequent.

How to reproduce

The repro could be broader than this.

1. Use my dual-monitor config with the relevant monitors.

Crash reports, logs, images, videos

I currently don't have time to repro with debug logging on. I may be able to later.

yikes, looks like a driver bug

is this exclusive to hyprland or does sway / wayfire have the same?

[deronparker]

Now that I think about it. I believe I remember a similar but less common issue when I would play video in XFCE -- and it was on a different monitor. So yeah, maybe a GPU driver problem. I might be able to try sway Thursday or Friday.

This smells like the hdmi forum to me. I've had this happen on my second dell vertical monitor I got from work. It only happens with hdmi and it only happens on my vertical monitor. A cablematters displayport to hdmi 2.1 adapter fixed these issues for me.

I have a 6900xt so its a different card generation but they both have the same issues with hdmi 2.1 for some reason. Also it only seemed to happen when going above hdmi 2.0 speeds so dropping from 4k60 10 bit color to 4k60 8 bit color should hopefully help if you have 10 bit enabled?

[deronparker]

I don't believe I have 10-bit on since my monitors don't have ,bitdepth,10 - src. Is there somewhere else I should check? @The-Briel-Deal

[The-Briel-Deal]

Explicitly set 8 bit, I believe 10 is default in a lot of cases without it. I think hyprctl monitors might show?

[deronparker]

With ,bitdepth,8 the problem persisted, unfortunately. I don't think this is a Hyprland issue, though. So, I'll close this indefinitely or until someone with the same issue comments.

Thanks for the troubleshooting @The-Briel-Deal

[The-Briel-Deal]

Ty! Sorry I couldn't be of more help! Lmk if you figure out how to repro.
