So Minecraft added lwjgl 3.4.1 support, using the -DMC_DEBUG_ENABLED -DMC_DEBUG_PREFER_WAYLAND flags, which when launching the game makes it run native on Wayland. When launching it using Xwayland (Minecraft on X11, running with a translation layer) doesn’t give that issue the performance is a little better actually, but running it native on Wayland gives a much much smoother experience genuinely and for me its kinda of a must have plus considering all major Distro’s Desktop Environments are Wayland only now, this must be fixed. On OpenGL the Performance between X11 and Wayland is the same, on Vulkan tho, I am loosing a lot of FPS when switching from X11 (or Xwayland) to Wayland.
For OpenGL there is are no issues with Wayland (except the cursor center reset problem which i did made a bug report MC-307253 note, this issue also happens with Vulkan, its glfw issue, you can fix it with custom patches which a lot of people have done over the community)
The first image is Xwayland/X11 OpenGL (452FPS)
The second image is native Wayland OpenGL (470FPS)
The third image is native Wayland Vulkan, (326FPS)
The fourth image is Xwayland/X11 Vulkan (631FPS)
Environment
Linux (Wayland)

Hi, Astr4x here the creator of the bug report. It looks like the image order got mixed up 😅.
So when I say something like “The first image is Xwayland/X11 OpenGL (452 FPS)”, that might not actually match the correct image. Please rely on the FPS numbers shown in each image to identify them correctly.
Thank you for your report!
However, this issue is Invalid.
Your game is modified, and you are using a third-party Java runtime environment. If you can reproduce the issue in a vanilla environment, please create a new ticket.
Any nonstandard client/server/launcher build needs to be taken up with the appropriate team, not Mojang.
A world which had previously been opened with a modified client might be corrupted. Please try reproducing the issue in a newly generated world.
Any plugin issues need to be reported to the creator of the plugin or resource pack.
If you have problems on large servers such as Hypixel, please contact them first as they use modified server software.
