on a SLES 15 SP4, where the VNC server is tigervnc-1.10.1-150400.7.5.2 , the
desktop is XFCE,
and the client is TigerVNC v1.12.0 (64-bit), users experience color and/or graphics issues with Firefox 102.5.0(esr) (64-bit), which causes trouble for them to perform certain tasks within browser interfaces so they are somewhat frustrated.
One characteristic of the issue is that certain areas within Firefox window appear as if those were in CMYK, like Google logo, SuSE chameleon, facebook on the following:
Others look normal:
So far I could find out that the color issue may be improved with, but neither did resolve the whole issue.
1. Setting in Firefox image.downscale-during-decode.enabled to false. This may improve the look like the following from www.suse.com
(left with set to true, right with false)
2. Disabling window compositor in XFCE, which causes the following difference (1st compositor enabled, 2nd disabled):
As it can be seen, the Firefox about window normally doesn't look like this.
Users sent screen shots of the following issues too.
Table header row and button colours:
White text on white background:
Table checkbox graphics issue:
I appreciate that this may not be the issue of TigerVNC but Firefox, however I wanted to ask here too as colour issues may be related to desktop graphics driver and I'm looking for any clues or idea about how this issue may be addressed.
Thank you in advance.
