I’ve already asked about fixing my green screen, but I now have thin parallel horizontal lines on 100% of my screen. Changing to dark mode the black is good but the white still looks bad.
hopefully the fix when it comes will sort out both green stripes and black lines.

iPhone SE, iOS 18
You may have a failing display or a failing motherboard on your iPhone. To understand the issue better, I recommend that you contact 👉 Official Apple Support OR you can always get your iPhone examined at the Apple Store 👉 Genius Bar Reservation and Apple Support Options or at an Authorized Service Center for further diagnosis and evaluation.

Burdy ~ The long process of applying an iOS update to an iPhone with a weak, aging battery can be the proverbial "straw that broke the camel's back." So...
Does your iPhone SE still have its original battery?
And what's the Maximum Capacity % here?...

As Axel Foley said the screen is failing. An existing weakness can precipitate during the stress of an update.
Don't wait for the next update wishing for a fix
Nothing to do with the battery either!!
Thanks again Alancito, just to further pass on more information, when checking my battery health there is a message/warning saying
”update finishing in background” I’m still getting flashes of green screens when I change apps but it is much improved.

If, by "Battery", you mean the Maximum Capacity % in Settings, that 80% level is when Apple suggests the battery be replaced. And I'm not familiar with that "update finishing in background”.

Burdy ~ Try this: At the top right of your Inbox, tap the 3 dots and choose List View. Then scroll down and see if that 1 unread mail appears. See the "Turn off categories" section at the end here:

Thank you I have put it into list mode (I really hate this update) it makes everything feel so much more difficult. The only way I can get rid of the 1 unread invisible email is to reboot the phone. Thanks for your help.
A failing display is always possible but the problem began immediately after the 18.2 update.
That makes a lot of sense, this morning after a night on my charger the display looks back to normal. Battery is still at 80% so you may be on the money thankyou 👍
well done.
Might be a product of the update but in my emails there it always shows 1 unread message when they are all read. I wish they had left the emails alone.
