Artefact showing on mobile website when using fixed height 100svh

[agasi]

Problem:
When in mobile grid an image is set to 'fixed height' 100svh and project is published, on my iPhone there is a black artefact showing in the top left corner on that project page, which should not be there. It started few weeks back after one of the Lay Theme updates. It's visible for me on these project pages, for example:

https://agasi.nl/electric-sisyphus/
https://agasi.nl/making-waves/

and also on another website I made with Lay theme (different ISP):

vloed.nu
https://www.vloed.nu/beneath-the-paving-stones-the-beach/

Check this project page: https://agasi.nl/test/ (bottom of the page) to see examples of what I am seeing.

• Tested on iPhone 16 Pro 512GB
• Tested on iOS 26.4.1 and 26.4.2
• Tested with latest versions of Chrome and Safari, same results. 
(tested on older iPhone with older iOS / Safari: not showing this)

As recommended in the forum I of course updated Lay theme and all Lay theme addons, disabled all plugins, turned off all custom code. No change, the problem persisted.

Maybe other users see this too?
Maybe one of you or Lay Theme Support team can see something on the pages that might cause it or debug it another way. Thanks in advance!

Best, Jos

Same problem, no solution yet. It only seems to appear when opening the website in Safari (mobile/desktop) and seems to be related to pages with Cover Feature when first navigated to (disappears on reload).

.svg-filter-wrap {
left: -9999px!important;
top: -9999px!important;
}

Can you put the CSS in Lay Options - Custom CSS and HTML?
Not sure if it's this that causes the issue, but yeah, please try that.
The CSS will be included with the next Lay Theme update.

Thank you! That seems to have fixed the issue.

I tried this, but it does not solve what I described. I have no issues on desktop, only on mobile, Safari and Chrome. See my original description and the test page I linked. Hope something can be found to solve it.

okay, can you send me your wp-admin login info to info@laytheme.com and a link to this forum topic?
