I just got back to Ubuntu Mate after a brief stint of distrohopping the past few months or so. Decided I'm finally gonna settle down, hopefully.
I'd usually remove Snaps, but I decided to give them another shot this time. Everything's fine and all so far, and I'm liking it. However, my App Center seems to be graphically glitching, kind of like flickering. Figured it might be outdated so I updated it through the terminal and all, still same same.
Everything works though, just that. I usually won't mind, but it hurts my eyes a lot. Any ideas? Thank you!
P.S.: I'd be happy to provide more information, just pretty clueless what else to add.
I don't see any issue, your graphics driver is i915 using the builtin UHD 620 chip. I tested app center on my um24, did not see any glitches. Maybe you can expand on that issue? others can help out.
I have the same exact graphics card literally the same one and I am not having any issues with my app center - although I do also have an Acer laptop so it might be something maybe with how Dell implemented it or something?
Have you had any similar issues with graphic display on any other distro you've used before?
And also - just a suggestion - have you tried to de-install and reinstall the app center via terminal? Maybe something happened with setup and is causing the flickering so reinstall might help
I've had graphical issues before on any other distro, just simple glitching. I think someone have also covered for it before in this forum so I add this to my /etc/default/grub.
I don't know whether I should disable my compositor. I'm not well-aware of the implications though I did have a non-composited setup back when I was with Xfce. If you don't mind, can you perhaps enlighten me on that matter?
That aside, yes, I do use Synaptic. Most of my package management happens in apt anyways. I usually just rely on App Center for my snap stuff, though I guess I could just use the terminal for that.
Oh yes - forgot to mention but now remembered - I disabled all those animations in MATE Tweak so maybe it is that:
To do that simply open system options in menu: look for "MATE Tweak" ---> open MATE Tweak and then you will see an option "Windows" on the left side of the app - Select "Windows" option and there simply un-check "Enable Animations" under performance - this solved all of the issues I had on my previous Mint setup whit MATE desktop as well and I just remembered it now since I kinda do it automatically every time I do clean install and just forget about it haha
Flickering on App Center only stops with disabling the compositor. I'm still trying to figure out why, because this definitely hasn't been the case before.
Thought of checking back... I flipped my compositor back on since I get pretty bad video playback when it's disabled. Issue still persistent on 24.04.2. Terminal tells me this.

Seems to me like you are missing some GTK modules based off of errors you've listed (but my searching skills may be wrong so take it with a grain of salt)
What I was able to find was that you may be missing " xapp-gtk3-module, appmenu-gtk-module, and canberra-gtk-module"
To add those modules and remove the errors connected to them :
Also - based off of your errors try and see if this command gives you anything:
ls -l /home/keiaa/snap/snap-store/1248/.config
"If ibus is a file instead of a directory, you need to remove it and recreate the directory."
Also if that won't fix the problems maybe try reinstalling snaps:
It seems to me it may be messy if done incorrectly and may cause errors so I would proceed with caution - maybe the simplest solution would be to freshly install 24.04.1 version and simply update via terminal to 24.04.2
Again, one thing that interests me - since you've mentioned in your first post that you usually remove snaps - did you by any chance remove them when you freshly installed Ubuntu MATE and re-added them or was this problem from the get-go?
All modules above are already installed. I recreated the ibus directory. Nada. I tried to reinstall Snaps. Nada.
This is a clean and properly working Ubuntu MATE (minimized) install. I didn't remove snaps when I installed this one, and the problem was indeed from the get go.
