Bug 465712

It seemed to stop when I switched my main screen to the 60Hz - the same refresh rate as my secondary screen - it was set to the 144Hz

Happens also inside the Wayland session. I can confirm that the monitor itself works fine under Windows 11 with refresh rate set to 144Hz.

I observe no flashes when I switch off my secondary display and switch main one to the 144Hz - so it works fine in single monitor mode.
What is interesting the flashes are there even on the SDDM screen, as soon as I boot my system. SDDM seems to force some higher refresh rate by default.

This isn't globally reproducible, can you try some tests to narrow this down

 - Was this definitely a non-issue on older Plasma?

 - Does this happen if you run a different (non-compositor) window manager. Can you run "openbox --replace" and see if goes away. That will show if the issue might be lower in the stack.

 - Can you run "kscreen-doctor --monitor" and rerproduce some flickering, to check if we're reconfiguring the monitor constantly

Yes. I was using 5.26 for very long time without issues.

Will check this soon.

Is --monitor a valid flag for kscreen-doctor? I get `Unknown option 'monitor'` and --help is not listing it.

To be also perfectly clear as how it looks like as I think that "flickering" undersells it a bit :P

I guess it should be "kscreen-console monitor". No, when this occurs no new stuff is printed by it.
But!
The flash occurs every single time I launch and close kscreen-console in terminal when monitor is set to 144Hz - will attach a link do video soon.

Using snapper I have booted a snapshot from before the upgrade. Now I'm at:

It also happens with openbox. This video shows behavior of kscreen-console for 60 and 144Hz. You can see the same flashes every time the kscreen-console is launched or closed while monitor is set to 144Hz: https://streamable.com/p0tzlx

kscreen-console is using libkscreen to slurp the screen config from the system and I see quite a bit of changes there lately: https://invent.kde.org/plasma/libkscreen/-/commits/v5.27.0 I wonder if the way forward would be to bisect it and check if something there influences it.

I can confirm that I am seeing the same thing on my pc.

> It seemed to stop when I switched my main screen to the 60Hz - the same refresh rate as my secondary screen - it was set to the 144Hz
I can confirm that 60Hz refresh rate fixed it for me as well. My monitors support 60, 120, and 240. All but of which besides 60 cause issues now.

> Was this definitely a non-issue on older Plasma?
Yes, I was running kde plasma 5.26 before with no issue

> Does this happen if you run a different (non-compositor) window manager. Can you run "openbox --replace" and see if goes away. That will show if the issue might be lower in the stack.
The same issue occurs when using openbox --replace although i do receive the warning

I just upgraded Fedora 37, and I am seeing this exact issue. Driving me insane.

This is on Plasma 5.26.5 so it's not just on 5.27 that this happens.

I can confirm disabling my 60Hz monitor and sticking to my 180Hz monitor solves it, but obviously that's not an actual fix.

F37 is now on KDE Frameworks 5.103.0? I think that libkscreen / kscreen are packaged in it and in my case, apart from plasma 5.26.5 -> 5.27.0, frameworks were updated to 5.103

Yes this also on KDE Frameworks 5.103.0.

I also tried kscreen-console monitor, and keeping it open while seeing the black screen flashing it doesn't seem to report anything. This is all it gave me while I saw it do it many times:

Remember to enable KSRandR or KSRandR11 in kdebugdialog

So that's not a way to detect it happening.

I can also confirm that matching the refresh rate on both monitors also fixes it, in addition to turning off one monitor.

This is somehow connected to the VRR / Adaptive-Sync / G-Sync. The problem went away when I disabled Adaptive-Sync in the OSD of my main monitor. For the record, it identifies as: Electronics-LG ULTRAGEAR-107NTZN7V189

I also see, that kscreen-console reports:

with vrrpolicy set to 2 - which if I understand it - means "Automatic". Is there some way to force it to 0?

This setting only has an effect on Wayland, where NVidia doesn't actually support vrr atm.

Is this still happening with 5.27.2 or newer? https://invent.kde.org/plasma/libkscreen/-/merge_requests/55 has been reverted in it because it caused other problems with NVidia, this might have the same cause

I can confirm that as of now it does seem to work properly :)

My HW setup changed a bit recently as my 60 Hz monitor died tragically. I now run two LG ULTRAGEARs - both capable of 144 Hz.

As soon as I switch Adaptive-Sync to ON in OSD settings of one of the monitors the flickering returns - even if both of them are set to 144 Hz. 
What is interesting is that when I turn Adaptive-Sync ON and then OFF I have to reboot my PC to get rig of the problem. Easy workaround in my case is to just turn off Adaptive-Sync to OFF on both monitors.

The situation from the time of original bugreport is also still valid - turning Adaptive-Sync to ON and setting both of the monitors to 60 Hz also fixes this situation.

I'm now running Plasma 5.27.4 on up-to-date openSUSE.

Thanks for the info.

I had this same issue, 144Hz main monitor, 60Hz secondary monitor, with the same Nvidia 2080Ti GPU. 
Fortunately, the issue was fixed with the latest driver release, I believe it was Version:	535.129.03
Release Date:	2023.10.31 (https://www.nvidia.com/Download/driverResults.aspx/213194/).

I have no more sudden black flickers of parts of the monitors when running at my preferred refresh rates.

In other words, I don't think this was a Plasma bug to begin with.

In my opinion this is resolved.

Jakob, have you also seen similar results.

Ah, sorry. I had both of my monitors set to 60hz for so long that I kinda forgot about this issue. The situation is as follows: both of my monitors are now set to 144Hz, both have Adaptive Sync enabled and nvidia driver is reported as of version: 545.29.06

I observe no flickering now :]

Great! And is the originally-reported issue of problems with non-matching refresh rates also fixed?

That is correct. I feel like this issue, for the scope it was originally created, can be closed now. Not sure if I should do it or how the rites require.

Thanks for confirming.

You can always close your own bug reports for whatever reason you have :)
