Random flickering screen - does seem to 'fix' on reboot
I've done some research and it seems more people have the same issue.
This video ain't mine (so far my issue ain't that bad only similar):
It can go days with no issues and then it happens usually starts when I'm scrolling through my mails on Outlook and when it does start even checking my apps on the dock (Dock's amplifier effect) triggers it as well.
Then I reboot and all is well for days…
What is that? Could it be faulty cable or a software issue maybe a firmware thing or even something with Mojave's Metal…?
Oh and I've seen the copy/paste reply sent to others online saying ‘replace display here's the guide’. That's not what I'm after.
First those displays are almost as expensive as the iMac itself but also other than this random flickering it works fine there has to be an answer other than the usual Apple motto ‘pay heaps of cash to replace or a truckload of money to buy brand new’.
This is iFixit, doesn't anyone knows how to fix this…?
After reading on MS forums many more people having issues with Outlook flickering screen on Mojave I downgraded mine to a previous version.
Actually tried as far back as 2011 but that wouldn't read my files and 2016 wouldn't even run on Mojave (all other Office 2016 apps would though) so I reinstalled Office 2019 and left it un-updated.
Current Outlook version is 16.19 will see if it still happens or not and keep this here updated.
Also gonna do the ‘heat management’ thing mentioned below anyway. Just gonna take a bit longer so the 'downgrading test’ still holds value I think…
An update on the issue: running a slightly outdated version of Outlook seems to have ‘fixed’ it. Haven't had ANY issues since so yeah it's either an Outlook problem or dark mode compatibility (in my case dark mode vs Outlook).
Either way it ain't hardware which is good news :)
What is not good news is the fact that the screen does have backlight bleeding which to be fair mine is hardly visible but once you see it you can't unsee it. :(
