Safari 17.2.1 shows graphics artifacts when scrolling

Hello Everyone

Just for your information, Apple’s latest update to:

macOS Sonoma Version 14.2.1 (23C71)
Safari Version 17.2.1 (19617.1.17.11.12)

has reintroduced Webkit bug 220892 that I previously reported during my CUBA development with this post:

This bug had been corrected, so this is a regression.

I am using Jmix 1.5.5 and the problem only occurs on my screens with multiple groupBoxes and tables; therefore, your application may or may not be affected.

The Webkit team has already begun their investigation and all of the information can be found here:

Bug 266926: REGRESSION(268028@main): Safari 17.2.1 shows graphics artifacts when scrolling
https://bugs.webkit.org/show_bug.cgi?id=266926

I will update this post with more information as it becomes available.

Best regards
Chris

Hello Jmix Team

For your information, Simon Fraser from the WebKit team wrote the following message in the WebKit Bugzilla ticket: 266926 – REGRESSION(268028@main): Safari 17.2.1 shows graphics artifacts when scrolling

There are a couple of things you can do to work around the bug. Remove this weird hack:

  <div class="v-expand" style="padding-top:1628px">
    <div class="v-slot" style="margin-top:-1628px"></div>

and remove this zero sized position:fixed:
  <div style="position:fixed;top:0px;left:0px"></div>

Unfortunately, there is no other information or explanation, so I do not know exactly where he found this code but maybe you can check the framework and correct/modify it if possible.

I will continue to update this post as soon as I receive more information.

Thank you in advance for your support.

Best regards
Chris

Hi, Chris!

Thank you for the detailed description and investigation, but, unfortunately, there is little we can do on our side. These “weird hacks” are the way Vaadin 8 layouting works, because Vaadin 8 and below layouting has been introduced before “flex box” era.

As an alternative, take a look at Jmix 2+ it has a modern layouting.

Regards,
