I would much prefer not to disable the animations. That would hurt the overall Zorin experience for me. I like how the OS looks and moves. So to me, it would not be a "cure," but a "band-aid." In any case, I feel as though now would be a good time to tag @AZorin and @zorink to see if they can provide a true fix, or at least explain what's going on with X11, why the mouse changes between Zorin OS and OBS Studio (in Wayland), and so on. I've tried different solutions, and plenty of you guys have chimed in, so it's time to tag the developers here. Hope they can help.
On a hunch, I downloaded Zorin OS 16.3 Core and put it on a live USB stick. Much to my surprise, in the live environment using my PC hardware, X11 worked perfectly. No glitchy window animations. Nothing. Absolutely nothing. Everything worked perfectly. I installed OBS Studio. The mouse did not change at all going from Zorin to OBS Studio and outside of OBS again into Zorin. Perfectly normal. To say I was shocked would be an understatement. Ha. (I exaggerate a bit, but still.) Why all this ... er, "stuff" with 17 when 16 works perfectly, yet is a lower version number? I don't get it. It's a regression. What happened? I just checked, and I see that Zorin 16 is on Kernel 5.15. Does that have anything to do with it? Would an update to a different kernel in Zorin 17 help? This is all a bit frustrating.
You can try the pop os kernel which is slightly higher (6.9.3) or downgrade to 5.15 kernel BUT in a month Zorin 17.2 will be upgraded to 17.3 and will also get kernel 6.11. Personally i would wait for that and “ignore” your little problem for now.
I thought screencasting was an issue for Wayland. I only use X11/xorg anyway on different OS and use vokoscreenNG to capture, then KDEnlive to edit and render to mpeg2 before uploading to Vimeo.
@AZorin announced here that the 6.11 Kernel will come:
But when the OBS-Version really have a Problem with the Wayland Implementation here on zorin 17, You should wait for Zorin 18 with a newer Desktop Version because it will - or at least should - have a better Wayland Implementation.
You could test another Thing if You are not against Flatpaks. OBS is available as Flatpak, too. So, it brings all the Stuff with it what it needs. So, You could try it with that.
I use obs for streaming and I've been Wayland only for quite some time now. Mainly to see what it's like, but it hasn't been causing many issues for me (being an AMD boi) so I've just kept on using it.
