TinyMce toolbox flickering

    An annoying issue just occurred after updating to WP 5.0.3.

    After placing image to a wysiwyg editor and trying to click edit button, the toolbox starts to flicker on hover, making the clicking impossible. Same thing when trying to add a link, all the edit functions are out of use because of the hover flickering effect.

    I suppose this is Gutenberg related issue since installing the classic editor fixes the issue.

    I did some research and issue seems to be related to a .tinymce-container, which seems to get display:none on hover.

    This was not an issue before updating the 5.0.3.

  • Hi, i am having the exact same issue, but only in Chrome and IE/Edge, it works fine in Firefox. I have multiple sites with Gutenberg and ACF wysiwyg editor fields, and the problem is present on all of the sites with WP 5.0.3

    My clients cant edit links in the wysiwyg fields when the popup link editor just blinks like crazy when you hover over the buttons in the popup.

    Has anyone found a fix to this problem?

  • I have updated to WordPress 5.1
    Updated to ACF Pro 5.7.12.
    Remove all other plugins.

    The issue is still here.

    The only way i have been able to solve the problem was to install Classic editor plugin.
    I’m seeing some sort of conflict between Gutenberg and ACF, but hoping ACF team to confirm it.

    Best wishes,

    @mikkor We have multiple sites that has the problem, and going back to classic editor plugin is a big hassle since our clients have been trained in Gutenberg now.

    We have opened a ACF Pro support ticket, and if they cant help us out soon we have to install that plugin.

    It seems it’s a TinyMCE bug since the issue was present is WP version 4.9.8 also

    I have also reported the bug there.

    Lets hope we find a solution soon.

    I found a crude fix by just adding 101% height to the body in Chrome and IE browsers in the edit post page.

    It works for now

  • Cool thing. Thank you for “the crude fix”. It works still.

    In my case the bug only presents when I have scrollbars set to always show in OS X, as described in that GiHub issue. When scrollbars are set to show “Automatically based on mouse or trackpad” there is no flickering.

    Until the fix finds its way into WP core that might be a workaround if you are on OS X.

  • After updating isuue is still there, please suggest me how to remove the errors
