Hello @Malay. Never mind - I' am not a native English speaker too. I have not tested the GUI intensively because my Goal is using this little board as a mini-server. Also, I think it's best getting the basics up before turning to the high-level GUI and media stuff.
The "current" 6.6.99 kernel seems not to work with Wayland. You can switch to X11, change /etc/gdm3/custom.conf. The "edge" 6.18.7 is works with Wayland. Integrating GPU support is out of my focus currently, I am even unsure if this applies for Orange Pi RV2: https://sdk.spacemit.com/en/graphics/graphics_driver_framework/ ?
HW Video decoding is another rabbit hole. The documentation is Chinese at best 🤪
Lowest price is what makes it popular. But software is the biggest key of the package and there they are among the worst.
On this SoC, we will be cooperating with SoC maker's board directly - working with Orangepi is too damaging for us:

This will probably be done in a couple of weeks, so you can follow that and adjust accordingly.
