Source code for the aperture size problem (which is probably just a performance issue): http://libdrm.sourcearchive.com/docum..._bufmgr8h_8497f60866d1d41552ed7002f9c2b450.html

It seems to happen also for EFL (Elementary) on FreeBSD/Wayland, but not in OpenGL acceleration, just on no acceleration: https://unrelenting.technology/tag?ta...

You might want to try to start blender with:

CYCLES_OPENCL_TEST=NONE blender

That should disable OpenCL in blender... I think.

This 'fixed' it for me, but it really needs to be addressed by the maintainer.

The following suggest that this is more linked to OpenCL than blender, and that the solution could be:

sudo dnf remove beignet

Beignet is an open source implementation of the OpenCL specification - a generic : compute oriented API.

Yesterday, for this question, someone suggested to try to install the flatpak version. Flatpak, is an inter-distribution format (push by Red Hat)... but I don't know how to use that yet.

https://developer.blender.org/T52262 seems to suggest the problem is link to Wayland, and exist from Fedora 26.

It seems to have been reported as a bug for Fedora 26 here: https://bugzilla.redhat.com/show_bug.... Looks like on the point to be closed because Fedora 26 is not supported anymore... Don't know what should be done in this case... open a new one on Fedora 28?
