Summary
Following the release of Google Chrome version 149, some CIMcloud sites may experience a visual glitch where radio buttons and checkboxes appear to jitter, warp, or shift during mouse hover. This is a cosmetic issue only — no data or functionality is affected.
Who Is Affected?
Sites running CIMcloud core version 2.0 through 4.15 that use the Portal template for sitefront pages may see this behavior. All Worker Portal pages are also affected.
Sites using the Retail template for sitefront pages are generally not affected (except for focus-style pages such as Create Payment and Payment).
The issue occurs in Chrome v149 and later on desktop. Other browsers (Edge, Firefox, Safari) are not affected.
- This is a cosmetic issue only — site functionality, form submissions, and data are not affected.
- The glitch is only visible while moving the mouse over the affected inputs.
What Causes It?
Chrome v149 introduced changes to its internal rendering engine that conflict with a broad CSS transition rule applied to form elements on affected CIMcloud sites. When Chrome tries to animate border and background transitions on native checkbox/radio controls, it causes sub-pixel calculation conflicts that produce the visible jitter effect.
Recommended Solution: Update to Version 4.16
The fix for this issue is included in CIMcloud version 4.16.0 and later. We recommend scheduling a Live Version Update (LVU) to resolve this permanently.
To get started, contact your CIMcloud or submit a support request to schedule your update.
Alternative Solution: Custom CSS Patch
If an immediate LVU is not feasible, a custom CSS override can be applied to your site to suppress the glitch. This is a lightweight customization that disables transitions on checkbox and radio inputs.
