Bug 2040771

I had all the packages listed, same versions, except egl-wayland, and I couldn't reproduce it. After installing egl-wayland, I still couldn't reproduce it.

What's your video hardware and driver?

Sorry

I forgot I have the system without NVIDIA Drivers installed, so, I have installed nouveau but the first graphic card is Intel.

If I use:

GNOME X.org Session:

DRI_PRIME=0 stellarium (or use stellarium without DRI_PRIME is the same behaviour)

However, If I choose Nouveau

DRI_PRIME=1 stellarium

I don't have the blink problem X.org or Wayland It's is the same. =)


So, the problem likes Intel.

00:02.0 VGA compatible controller: Intel Corporation HD Graphics 630 (rev 04) (prog-if 00 [VGA controller])
01:00.0 3D controller: NVIDIA Corporation GP107M [GeForce GTX 1050 Mobile] (rev a1)

It works on my intel: 00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)

Looks like a driver bug.

I've tested this one: https://bodhi.fedoraproject.org/updates/FEDORA-2022-b5fb1111d8

But It does not solve the problem.

It's not a Xorg problem, redirect to MESA

https://gitlab.freedesktop.org/mesa/mesa/-/issues/5731

I've performed some tests.

Stellarium 0.2.3 with MESA Drivers 21.3.4 - Causes blinks bad works.
Stellarium 0.2.3 with MESA Drivers 21.3 - Causes blinks bad works.
Stellarium 0.2.2 with MESA Drivers 21.3 - Causes blinks bad works.
Stellarium 0.2.2 with MESA Drivers 21.1.8 - Works fine.

This software runs with this packages:

mesa-libGLU-9.0.1-5.fc35.x86_64
mesa-libglapi-21.3.4-1.fc35.x86_64
mesa-libgbm-21.3.4-1.fc35.x86_64
mesa-libEGL-21.3.4-1.fc35.x86_64
mesa-libGL-21.3.4-1.fc35.x86_64
mesa-filesystem-21.2.3-6.fc35.x86_64
mesa-dri-drivers-21.2.3-6.fc35.x86_64
mesa-libxatracker-21.2.3-6.fc35.x86_64
mesa-vulkan-drivers-21.2.3-6.fc35.x86_64
stellarium-0.21.3-1.fc35.x86_64

I've perform:
sudo dnf downgrade --version mesa-dri-drivers-21.2.3-6.fc35.x86_64

That's works.

The problem is MESA.

I've rebuilt a Mesa package with a patch to solve this problem.

THIS WORKS!

SOLVE THE PROBLEM WITH PATCH APPLIED IN THE PACKAGE

Sorry, I'm recompiling the SRC to send a Koji with commit used inside the package and mail in the changelog.

You can get the latest packages with comments included from here:

https://koji.fedoraproject.org/koji/taskinfo?taskID=81298037

I don't know how I can send this to Bodhi for test.

0007-iris-solve-blinks-problems.patch

New build because Mesa 21.3.3 was updated to 21.3.4

That does not solve the issue.
