A new problem has arisen in Safari prefs and Videos on my mac since upgrading to 10.15.2 - Buttons in Safari's preferences have a red colour as they load, a bit like a background highlight. It only lasts a fraction of a second as the pages drops down but it has the feel and look of a virus. And, Video's from places like Youtube have a highlight colour usually green like a badly compressed or incompatible clip, again as if quicktime has a virus and only since the update to 10152? Shame there isn't an open firmware reset anymore to weed out all the possibilities. Any help would be much appreciated
 
Could it be the new reported security glitch in Safari? Have I been hacked or harvested? Is this only a Safari flaw or is it affecting compression algorithms across the OS? So many questions so few replies.....
 
Are you talking about a red square, about 1mm x 1mm that appears occasionally in the title bar, and on some HTML5 videos? Seen this and I believe it to be a known issue.

No it's as if the prefs buttons contained in each prefs option in safari have a background highlight colour as the page drop down, so visible only for a fraction of a second, and more and more video clips are starting to show bright green/red halo's in shaded regions of clips which gets worse if the window is moved. It reminds me of a very old quicktime bug to do with 3rd party mpeg compressors but this only began after I updated to 101502 and now we have this news

 
I've just discovered that colour glitch appears on any highlighted pref option and buttons if the menu bar is picked up and waved around the screen so it's as if something is running in the background of Safari?
 
Try turning off True Tone - and check your colour profile - I had similar issues with 10.15 when using a X-Rite calibration device, and custom profile that wasn't Color LCD.

Thank you xnsys. Problem appears solved - 2 copies of the same profile and it was the new one/vers that was causing the glitch in safari I'll keep testing the catalouge of glitches I've been building since installing the .02 update and see if the old profile rectifies them all !!!! I never thought to look at the date and vers of the profiles. Thanks again - I can sleep finally

Spoke too soon, now the glitch is appearing in finder windows but not safari prefs!
 
I've seen this behaviour on several machines in the corporate world - it all does appear to be with the monitor settings - and it's completely random.

For one machine I had to manually delete all the Color LCD profiles in the Main HD > Library > ColorSync > Profiles > Displays - and remove everything in there, reboot and it seemed to resolve the issues - once deleted you will need to reboot and it will re-create the profile.

The settings that I've found most reliable are to disable True Tone, also the auto adjust brightness and then use a custom calibrated profile.

As I've said in previous threads, there is a lot wrong in 10.15.x, but the majority of these issues are not evident to the home user, for anybody doing anything slightly more complex then they get annoying.

In all honesty, I would recommend either putting up with it, or like we've had to do....roll back to 10.14.6 and skip 10.15 all together, there isn't a great deal in 10.15 that's going to assist you in day to day activities.
