Public bug reported:
I have an Ice Lake laptop (Dell 7390 2-in-one) which I am connecting to
a TV over HDMI via a Novoo USB-C multiport adapter. This is not a
Thunderbolt device, it is just USB-C.
It seemed like things used to work fine before I upgraded this system
from Ubuntu 19.10 to 20.04,
The color distortion resulting from this change is very glaring; not
even close to accurate color. So either this change should be fixed,
reverted, or color management should be disabled by default. All of
these solutions are simple; the broken attempt at color management is
not.

This also affects me (identical IP in the segfault) but I don't have any

Maybe that's because it was upgraded from Focal? Seems like the probable
cause at least on my machine

The fix in the PPA is not working for me on Jammy: the lag may be gone,
but some rendering is intermittently missed.
Some info:

Hi Daniel,
No, not multi-GPU. It's an AMD system with no integrated graphics and
only one Nvidia card. One monitor plugged in, one TV plugged in to that
card via HDMI. But the TV is usually turned off, and disabled in
Settings | Displays. Running Xorg, not Wayland.
This doesn't look like bug
Dropped all the `savoury1` PPAs from my system and will keep an eye on
this to see if I can find a way to reproduce it.

too much work. I'd make sure all the related packages are removed before
installing 535.
Might help the developers to know what version of Ubuntu you're running.

Everyone's been discussing bug 2007742 as something that causes only log
spam, no other issues. My system is still failing to update the screen
after keypresses in gnome-terminal. So maybe those log messages aren't
relevant, but it looks like this bug 2059847 is not fully & correctly
fixed.

Upstream Gnome 46 made a lot of changes recently to improve performance
and input lag in Gnome-Terminal. Those changes are separate from this
bug. I don't know whether those changes were backported to Ubuntu 22.04,
which ships Gnome 42. That's a question for Daniel or someone else at
Canonical.
