System Information

Operating system:	Graphics card:	Report:	Owner:
Linux-6.4.9-200.fc38.x86_64-x86_64-with-glibc2.37 64 Bits	NV118 Mesa 4.3 (Core Profile) Mesa 23.1.6	#111314	@Bird_Lunch

Blender Version
Broken: version: 3.5.1, branch: unknown, commit date: 1970-01-01 00:00, hash: unknown
(It looks like Fedora's package manager breaks commit information.)
Worked: Looking at other tickets, the last working version seems to have been 3.3.

Short description of error
As reported in a couple other issues, Blender's object view shows as transparent when the program is opened.

I also noticed that, in edit mode, the dots indicating vectors and faces are unusually small – almost too small to see. They appear to be only 1 pixel in size. I haven't noticed other tickets mention that symptom.

I'm using Fedora distribution, GNOME desktop environment, and Wayland windowing system.

Exact steps for others to reproduce the error

Install Blender using the dnf package manager on a Fedora Linux system running Wayland.
Launch Blender from the "Activities" window. As a reminder, this uses the blender.desktop file to launch Blender.

Looking at other tickets, using Fedora does not appear to be a prerequisite to reproducing this bug.

Workarounds
After fiddling with it a bit, I've found some workarounds that may prove illuminating. Here are some changes that cause Blender to behave as expected:

Run Blender in full-screen mode. As long as the user stays in full-screen mode, the background is rendered as expected. This does not solve the node issue. You can see this in the second screenshot.
Launch Blender from the terminal. For example with blender &. This solves both problems.
Launch Blender by double-clicking it in the File explorer. In my case at /usr/bin/blender. This solves both problems.

Basically launching Blender by any method other than the .desktop file seems to solve the issue. I launched a download of Blender 3.6 this way, and did not see the issue, though in that case I couldn't easily launch the .desktop file to replicate the bug.

Here's Blender 3.5 running on the same machine, launched from the terminal using blender &. You can see that, even windowed, the background is opaque and the vector nodes are the right size:

Duplicate Issues
I opened this fresh ticket because I haven't seen anyone mention the node issue, or how launching Blender in different ways affects this bug; I wanted to add that information to the discussion.

The original ticket appears to be #102994.
This issue also appears to be duplicated in #104035, #110327, #103152, #115764, and #103483.

Managing My Expectations
From the other tickets, I get the impression that this is an issue with drivers, and is out of scope for the Blender team to fix. In lieu of a fix, I would love to see this workaround info added in a place where other users with this problem can find it.

Thank you for your hard work on Blender! I hope this ticket is helpful.

In issue #104035, user @Laurent-1 claimed that this issue causes NVIDIA driver crashes and kernel errors in their Ubuntu environment. I haven't experienced these kinds of errors in this ticket, so I wonder how related they are. I encouraged Laurent to try the workarounds documented here and report whether they help.
