It is already using plasma 6 since a few weeks back, or am I miss interpreting something?

This must be some sort of wetlander-humor

It un-fucked itself thankfully, I haven’t done anything to resolve that issue. But when I ran the update today it went well with several new packages. Which means Nobara or Fedora pushed some changes to packages in the repos.

Yeah I forgot to mention that I’ll not be using dnf manually but rely on nobara-sync. But I must stress that I already did that before this issue, BUT I followed advice on nobaras own website where the solution was to use dnfand I still ended up with this problem. The real issue was still my own though, I should have upgraded to Nobara 38 before trying the workarounds, since 37 isn’t supported any more.

Yeah I kind of realised that the instructions assumed I had already upgraded, will try to keep track of new updates better in the future. So for sake of completion here’s how I solved it in the end:

• Ran upgrade from Nobara 37->38 following their guide: https://nobaraproject.org/docs/upgrade-troubleshooting/how-do-i-upgrade-to-a-new-nobara-version/
• Ran into conflicts: file /usr/lib64/libopenh264.so.2.3.1 conflicts between attempted installs of openh264-2.3.1-2.fc38.x86_64 and noopenh264-0.1.0~openh264_2.3.1-2.fc38.x86_64
• Solved it with exclusion: sudo dnf -v system-upgrade download --releasever=38 --allowerasing --exclude=openh264.x86_64
• Fonts and glitches are gone, got some broken deps instead. So if anyone got a suggestion for that instead let me know. Otherwise I’ll do as it suggest --best --allowerasing' and see what else breaks:

Problem: The operation would result in removing the following protected packages: plasma-desktop

That is helpful, I’m not sure what I’m looking for yet though. But another comment lead me into antialiasing and this line in the history seems plausible.
install -y /tmp/zenity/nobara-amdgpu-config/fedora-amdgpu-pro/packages/amdamf-pro-runtime-5.4.3-4.fc37.x86_64.rpm /tmp/zenity/nobara-amdgpu-config/fedora-amdgpu-pro/packages/amd-gpu | 2023-04-25 20:11 | I, O | 11

Undo didn’t work though:

sudo dnf history undo 11
Error: The following problems occurred while running a transaction:
Cannot find rpm nevra “amd-gpu-firmware-20230404-149.fc37.noarch”.

So I made a rollback to my last know stable point: sudo dnf history rollback 2
It didn’t exactly workout either unfortunately:

I’ll do a reboot and see what actually took effect. Atleast I’m learning something, maybe I should do all my upgrades via dnf instead of the manager in the future, easier to know whats going on.

Turning AA off for fonts solved the missing characters, downside it doesn’t look very good. I still have glitchy artefacts in some menus and the package manager doesn’t display any text for buttons which is a bit problematic. Guessing disabling some more AA settings would remove more of the problems. But it doesn’t solve my main problem - why did AA break in the first place

I pretty new to Linux gaming but I love it. Currently playing games directly from Steam and Blizzard games via Bottles. Please help me out with a few questions. What is the use case for gamescope? What is the use case for Heroic? Is it instead of Bottles/Lutris?
