I think this maybe Mesa related as when broke Mesa bug disappeared. G41 Intel onboard is running main monitor & AMD passively cooled GPU runs second monitor. I run it this way so as to enable proper hibernation & sleep. Running both monitors from GPU used to be buggy with Hibernate & sleep. So yeah, probably ancient G41.

Comment 2 gtx.swift 2023-07-04 11:46:07 UTC

Confirm as not present with running both monitors running off PCIE Radeon HD6450. However now PC does not resume from hibernate, so guess will be posting a secondary bug via openSUSE Bugzilla.
