Hi all! I’ve been running into the following issue of late. More and more frequently I notice fonts and symbols getting scrambled up on certain apps, mostly my terminal (kitty) and VS Code. Here is what I mean
As is mentioned in the topic title I’m on F42, Gnome 48.2, mutter 48.3, kernel version 6.15.3-200.fc42.x86_64, with proprietary NVIDIA drivers at version 575.64.
This hasn’t happened to me before, so I’m not entirely sure about what might be the issue. Any advice/insight would be much appreciated. Thanks!
Oh, and I’m also on Wayland using both my discrete and integrated GPU like normal.

Have a look if you’re not hitting this issue regarding nova-core.

Upon inspecting the /etc/default/grub file, it looks like nova_core is already blacklisted:

Also, here is the output for the command sudo dmesg | grep nova_core:

I remember seeing somewhere that nova-core should be written with a dash (nova-core) and not underscore (nova_core) when blacklisting.

I don’t see nova-core in the dmesg output

What I meant was to replace these existing kernel arguments:
rd.driver.blacklist=nouveau,nova_core modprobe.blacklist=nouveau,nova_core
with these:
rd.driver.blacklist=nouveau,nova-core modprobe.blacklist=nouveau,nova-core
There are reports stating that both nova-core and nova_core should work the same, but I guess it’s worth a try.
What is the output of the following:
$ modinfo -F version nvidia
$ uname -r
$ dnf list --installed "*nvidia*"
Please post your outputs as proformatted text and not as screenshots, there’s nothing to understand from those.

I do not have the problem on VSCode with Nvidia driver 575 like yours if it is going to help your case.

I think v575.64.03 of the NVIDIA driver fixes this issue. I haven’t experienced it yet since upgrading the driver version. Let’s hope it stays that way
