Has anyone else noticeds Fusion 13 Debian 12 vs Fedora Rawhide GPU Issues?

[AlexKite]

I'm running Fusion 13.0.2 on an M1 Max with the latest Debian 12 and Fedora Rawhide (also tried Fedora 38) out of the box GNOME installs. Both VM's have identical hardware settings.

To my surprise Debian 12 works almost flawlessly. Using Chromium I'm able to play 4k youtube videos without a hiccup in video or audio. Where as Fedora Rawhide or 38 can barely open and play a video. Browsing with FireFox on Fedora also creates artifacts on majority of websites where as it works fine in Debian 12.

I've glanced over a few of the differences but kernel and packages looked relatively close. Just wondering if anyone noticed a similar issue and may have figured out what settings Fedora may be missing?

Thanks!

I’ve not seen the Firefox issues on Fedora but then again I haven't extensively tested it.

Are you running the VMs with 3D acceleration enabled?

One thing I've done in both is to tweak the sound driver configuration in both distros per advice in https://communities.vmware.com/t5/VMware-Fusion-Discussions/No-sound-in-Linux-on-Apple-Silicon/m-p/2...

I've opened a couple of YouTube videos and haven't seen issues either on both platforms. 

I don't use Chromium, but I haven't noticed any artifacts - but that could be because I haven't been looking for them.

Any examples of web sites and/or YouTube videos that are giving you problems that I can use to see if I'm seeing the same things?

Yes, both VMs have 3D acceleration enabled.

With Fedora the issue is on any youtube video. The reason I was using Chromium is because FireFox doesn't give the option for 4k on youtube. Playback on Fedora seems like the acceleration is not even there. It stutters at a few frames per second and the sound chops. I'll check the sound solution and see if that may resolve this.

The website I noticed the most FireFox issues is on Foreman (Satellite). Certain windows just tear and/or do not redraw properly. Chromium doesn't have these issues in Fedora but neither FireFox nor Chromium have these issues in Debian 12. (both have open-vm-tools installed).

I'm not using these VMs for watching videos and general browsing, it's mostly work stuff. The videos were just a way I was testing the new laptop. Now that I think about it, I also had similar playback issues with Fusion 13 on an Intel MacBook Pro and CentOS 8.4. But I didn't really give too much thought to it. I was just pleasantly surprised how well Debian 12 worked on the Apple Silicon. Since most of my work stuff revolves around RedHat I'm a bit more used to the environment and was curious what may be causing this difference.

Thanks!

Thanks!

Thanks for the suggestions! Disabling and/or removing the sound card from the in Fedora 38 VM fixes the stuttering video in Chromium and FF. So it's not the GPU acceleration.

However none of the fixes suggested in the other thread worked for me to fix the sound. The 50-alsa-config.lua files are identical between Debian 12 and Fedora 38. The pipewire.conf were slightly different. I tried making all the suggested settings, making pipewire.conf identical but neither made even a slight difference. I tried downgrading pipewire-pulseaudio but the Fedora version was still slightly newer than what comes with Debian 12 and also made no noticeable difference.

Strangely disabling the sound card seemed to also resolve the FireFox artifact issue I noticed. I didn't test it intensively but I couldn't recreate it.

Oh well, not using these for entertainment so audio is not required and now I know what to look for.

Thanks again!

Something else I just noticed. If I do a live disconnect of the sound card and immediately reconnect it the audio starts working in Chromium and FF. However if I close the browser and restart it, it starts to chop until I do the disconnect/reconnect.
