Marc-Andre - can we get this backported for 9.3.0 please. If you'd like to provide thoughts related to a 9.2.0 z-stream please do so. I'm not convinced without proof that this would affect our LPs like OpenShift or OpenStack
(In reply to John Ferlan from comment #5) > If you'd like to provide thoughts related to a 9.2.0 z-stream please do so. > I'm not convinced without proof that this would affect our LPs like > OpenShift or OpenStack It should be as "easy" to backport for 9.2.0 (qemu-kvm-7.2.0-14.el9_2.N ?). Indeed, I am not convinced many users are using the PNG format, and it's not critical either to have bad colors.
QE bot(pre verify): Set 'Verified:Tested,SanityOnly' as gating/tier1 test pass.
Verified this issue against qemu-kvm-8.0.0-9.el9.x86_64, screen capture with png format show correct color
