Blender Version
Broken: version: 3.6.0, branch: makepkg (modified), commit date: 2023-06-27 08:08, hash:

Short description of error
I can see my wallpaper through the viewport as seen here;
I tried it with i3 instead of sway it worked fine, this is a wayland specific issue
Running blender from the console gives me 6 of this error
and one of this error
I reproduced this bug on the version of blender on the website and also the daily build. Please let me know if there's any other info I can provide to help.
Exact steps for others to reproduce the error
[Based on the default startup or an attached .blend file (as simple as possible)]
After a bit more digging on my part I found this forum post about wayland support. Has wayland support not been merged in?
The wayland support is already in, but somewhat buggy.
This is different from #102999, you only have a viewport that's blank, suggesting it not being drawn in any way. Could be driver issue,
NVE6 Mesa 4.3 (Core Profile) Mesa 23.1.3suggests you are probably not using proprietary driver from NVidia? Usually using their driver can result in less trouble overall.Viewport is transparent on waylandto Only 3D Viewport region is transparent on waylandCould you try with official Nvidia drivers as Yiming said? I guess Nouveau drivers are not supported.
Similar issue has been reported before with Nouveau drivers drivers, see: #104035 / #102994
After trying out the proprietary driver, the issue does not occur! However; pretty much everything else surrounding blender breaks. Most wayland compositors straight up refuse to boot off of nvidia instead of nouveau. I got Plasma to work with nvidia and tested it that way; but everything was so slow that it was basically unusable. (There were 3 seconds between me moving my mouse and it updating on screen).
So while Blender might work better with proprietary drivers, wayland seems to very much not; or so says my experience.
I notice that the tag still reads "requires info from user", how else can I help?
Only 3D Viewport region is transparent on waylandto Only 3D Viewport region is transparent on Wayland (NVidia + Nouveau)Listed this report from #76428 however nouveau drivers are known to have many limitations compared with NVidia's drivers.
Closing this report as NVidia's drivers having poor (even broken) Wayland support is also out of our control.
This is a documented limitation:

Should this be marked as a duplicate of #102994? These appear to refer to the same issue, and #102994 is the earliest iteration of this ticket that I can find.
Seems to be the same yeah.
