Happy you solved it.MiracleDinner wrote: ↑2023-01-01 18:01 Okay so this morning I reinstalled Debian and I can confirm that, on an entirely fresh installation using the Calamares installer live nonfree xfce 11.6 iso, the glitch does occur.
Yes, it looks like it's not installed now.MiracleDinner wrote: ↑2023-01-01 18:01 @Aki I didn't see your post until after I did this reinstall, but running this tells me it's not on this new install?Code: Select all

I did not say the glitch was solved. It's not solved - I still experience it exactly as before, the lightdm-gtk-greeter almost always has it and slick-greeter ocasionally has it. My post was to say that the glitch happens even on an entirely untouched new installation meaning it's not the case I misconfigured something or left some artefact behind that's causing it.Aki wrote: ↑2023-01-01 22:39 Hello,Happy you solved it.MiracleDinner wrote: ↑2023-01-01 18:01 Okay so this morning I reinstalled Debian and I can confirm that, on an entirely fresh installation using the Calamares installer live nonfree xfce 11.6 iso, the glitch does occur.

Maybe it will be fixed in 4.18.I'm also not entirely happy with changing to it so I'd still like a fix for xfwm
Speaking of which, and I apologise for not bringing this up earlier, but I did try installing sid (or more specifically what I did was used Calamares from the live nonfree xfce iso for Debian 11.6 and upgraded to sid from there) and I experienced the following glitch:
Sad to hear that. I think there are two ways out in this case. The first is to accept it and use it, and the second is to use another window manager.MiracleDinner wrote: ↑2023-01-03 16:42 I'm now running XFCE 4.16 with XFWM 4.18 and I experience the black flicker sans rainbow flash exactly as in the video attached to my previous post.
You can use the module_blacklist kernel option [1] to disable temporarily (at boot time) the loading of nvidia kernel modules (drivers):MiracleDinner wrote: ↑2022-12-19 09:43 If your hypothesis is that it's caused by the NVIDIA hybrid graphics, is there any way that I could verify this? E.g. might it be possible to entirely disable the NVIDIA GPU and see if the glitch still happens? I do note that I believe this glitch occurs regardless of whether I use the proprietary drivers or the nouveau drivers.

Do not load a comma-separated list of modules. Useful for debugging problem modules.
Hello. This is not fault of nvidia drivers. This is problem in xfwm4....

Hello. What video card are you using?Aki wrote: ↑2023-01-05 13:16
Thanks for your note. So far, I wasn't able to replicate the issue with the current Debian Stable (11.6) in a KVM installation (using lightdm and xfwm4 [1]).
I tested it with a graphic card different from the OP's ones (the graphic hardware of the OP is not available to me).
