[SOLVED] App screen freezing while still being responsive

I can't find the cause of the bug, I am not able to reproduce it willingly.

With some apps (Deezer, Discord, Zoom, the new version of firefox (not the old one), sometimes (often) when I switch to the workspace or after waking up my laptop from its resting black screen, the application is displaying a frozen screen but is still answering to keyboard and mouse, I just cannot see what is going on, the screen displayed is the one from the workspace I come from or the frozen version of the app. When I click in the place of the firefox tabs i can see the title of the window change but the content stays the same.

Sometimes with Discord of Deezer, if I wait for a while, it comes back. Refreshing i3 does nothing. I was not able to find any useful logs.

I had notice something similar when dunst was not running and the app like Deezer was sending some notification. If dunst was not running it would freeze until I start dunst.

Configuration :

- i3
- x11
- dunst

I had trouble finding people with the same problem.

Thanks in advance for your help.

Re: [SOLVED] App screen freezing while still being responsive

Welcome to the boards

That's a 3D controller nvidia card, did you set something up that would make this actively used? By default this isn't going to do anything and everything will be rendered by the intel integrated card. And symptoms here sound like the typical issues with xf86-video-intel which I suggest you uninstall if it's currently installed.

Should that not suffice, post your xorg log and a

sudo journalctl -b --no-pager

, and please use and edit your previous post to wrap command outputs and file information in

[code]code tags[/code]

Re: [SOLVED] App screen freezing while still being responsive

Thank you,

It seems like removing the package xf86-video-intel (and rebooting) fixed it thanks ! There was nothing in journalctl. Here is my x11 log https://pastebin.com/xKpFRkBD after reboot.

It seems like I use both controller :

lspci -k | grep -EA3 'VGA|3D|Display'
00:02.0 VGA compatible controller: Intel Corporation UHD Graphics (rev 05)
	DeviceName: Onboard - Video
	Subsystem: Dell Device 09c2
	Kernel driver in use: i915

01:00.0 3D controller: NVIDIA Corporation GP107GLM [Quadro P620] (rev a1)
	Subsystem: Dell Device 09c2
	Kernel driver in use: nvidia
	Kernel modules: nouveau, nvidia_drm, nvidia

I am thinking to to install a compositor like picom
