VNC desktop with wrong colours
Description of problem:
Colours of VNC desktop in vncviewer on ppc64 are wrong and there is also some repainting when moving window or select/highlight with mouse.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. $ vncserver :1
2. $ vncviewer :1
colours of desktop are wrong
colours of desktop should be correct
It is very probably endianness problem. Tested with vncserver running on ppc64 and x86_64, vncviewer on ppc64 had always wrong colours.
Via Vinagre colours of VNC desktop are correct.
Do you have chance to test on RHEL 7.5 with older Xserver and tigervnc? I would like to know whether it's a regression in RHEL 7.6 or whether this has been a problem for a long time.
Yes, I have. I will test it as soon as I will have ppc64 machine reserved. It should be at latest by tomorrow.
Wrong colours are also present on RHEL 7.5 with:
gnome <= 3.26
Fixed with tigervnc-1.8.0-10.el7.
Desktop colours now looks correct with tigervnc-1.8.0-10.el7.ppc64. Switching to verified.
(However there remains small issue, that popup with "Press F8 to open the context menu" is blue tinted. Filed that to bug 1618777.)
