Until this is fixed, you can manually modify an internal Cognos CSS file to fix it.
In \analytics\webcontent\bi\pat\hal\hal.css and \analytics\webcontent\pat\hal\hal.css
Find and change the following:

to:

IMG.clsLVRadio,
IMG.clsLVRadio_checked,
IMG.clsLVRadio_checked_disabled,
IMG.clsLVRadio_disabled,
IMG.clsLVCheckbox,
IMG.clsLVCheckbox_checked,
IMG.clsLVCheckbox_checked_static,
IMG.clsLVCheckbox_static
{
height: 16px;
width: 16px;
/* This prevents the radio and checkbox images from shrinking when there isn't enough room */
min-width: 16px;
vertical-align: middle;
}
to
IMG.clsLVRadio,
IMG.clsLVRadio_checked,
IMG.clsLVRadio_checked_disabled,
IMG.clsLVRadio_disabled,
IMG.clsLVCheckbox,
IMG.clsLVCheckbox_checked,
IMG.clsLVCheckbox_checked_static,
IMG.clsLVCheckbox_static
{
height: 18px;
width: 18px;
/* This prevents the radio and checkbox images from shrinking when there isn't enough room */
min-width: 16px;
vertical-align: middle;
}
For some reason under 18px the checkboxes don't show up consistently. I believe this might be a bug introduced in the latest Chromium release, but this should fix it in the meantime.

Subject: Checkbox disappears in Value Prompt object
We noticed the following phenomenon in an HTML Report only in the last 2 weeks (worked fine before that):
In a Checkbox value prompt with "Select UI" set to "Check box group" the check boxes next to the items are mostly not displayed when unchecked. When checked the box becomes visible.
This behavior is somewhat inconsistent: The list the last visible item in the list has the unchecked box displayed while for all the items above it the unchecked boxes are not displayed. When clicking to check the box, the checked boxes are displayed correctly.
When scrolling down in the list, the unchecked box does appear for every new at the bottom of the list that becomes visible during scrolling but then disappears as soon as the item moves up and a new item becomes visible at the bottom of the list.
This happens in both Chrome (Version 93.0.4577.63) and Edge (Version 93.0.961.38) in CA 11.1.7
Any ideas about the cause or the solution?
