[SOLVED]Some applications very slow when connected to external monitor

Hi,
I have a Thinkpad X1Extreme gen 1 with Nvidia 1050. When I connect to external monitor some applications seem to be very slow to respond.
Ex; surf, qutebrowser, nyxt are very slow. When I type anything it takes like few seconds for me to see that change on the applications.
I faced this on chrome, visual studio code and disabling hardware acceleration seemed to fix for these apps but not sure if that is an option available for all the apps that are slow to respond when connected to external monitor

Anyone faced this issue? Or know how I debug this issue?

TIA!

Re: [SOLVED]Some applications very slow when connected to external monitor

Is the internal display off/the lid closed? There's a bug in the current nvidia driver constellation where that can lead to this, check for that and generally you might also want to make sure PRIME sync is enabled by enabling modesetting https://wiki.archlinux.org/title/NVIDIA … de_setting

https://wiki.archlinux.org/title/PRIME#Reverse_PRIME - blue note.
https://gitlab.freedesktop.org/xorg/xse … ssues/1028

Try to disable DRI3, "export LIBGL_DRI3_DISABLE=1" w/ the modesetting driver.
For xf86-video-intel see https://wiki.archlinux.org/title/Intel_ … RI3_issues - but you probably don't want to use that driver anyway.
