Black Rectangle Seen When Pointin At Buttons

[anonprivate]

When I point my mouse to a button I see a black rectangle rather than information. Is this expected?

[TWPonKubuntu]

I think what you are seeing is the 'tip' text box with the color scheme set to black text on black background. If you look very closely at the box, can you see faint text?

Got to Settings->Application Appearance->Colors->Color tab and change two color settings:

Button Background (I use a light white or gray color)
Button Text (I use a White text color to contrast against the gray background)

Thank you for responding.

My colour schemes look fine.

As an example of my problem, when I point the mouse towards 'Reply With Quote' on this page all I see is a black rectangle. In addition smileys, 'Reply' button, 'Edit Post' button, and other icons are also seen as black rectangles.

Try changing the Desktop Theme.

I think that's what TWPonKubuntu is addressing for you. This issue seems to have arisen with latest updates to Firefox. By changing the color scheme (as noted above by TW), you can then read the content of those "black boxes" you are seeing. Try it, remembering your changes so you can undo it. Change the colors specifically as in post #2, write down what you did, re-start Firefox, and try it.

Added: Btw, I am assuming you use Firefox here.

I like the colour scheme. I am wondering if changing the source for widget or dialogue background might help. I also wonder if a change in Firefox could help.

Under Kubuntu 14.04.

I'm using Firefox 46.0.1 now, with no problems on icon display. My Firefox Theme is "Carbon Light".

Firefox 47.x has just been released and Debian/Ubuntu will shortly issue an update, so watch for that.

Which Kubuntu Theme are you using?

I am also using Firefox 46.0.1.
My desktop theme is Oxyglass.

How did you configure Firefox for 'Carbon Light'

[TWPonKubuntu]

In Firefox, click the "Open Menu" icon (Three dark bars) which is on the far right of your tool panel.

Select "Customize" and then the button "Themes" at the bottom of the screen.

You should see a list of theme options. If "Carbon Light" is not on your list, use the option to "Get More Themes".

DO remember which theme you are currently using, so you can return to it if the a newly selected theme does not work for you.

See this post. Did add the PPA:

Same thing happen with previous Firefox upgrade and Plasmazilla solved the issues (black rectangles, dysfunctional Nautilus instead of Dolphin, etc...). Lets hope the Plasmazilla upgrade will come soon!

I tried 'Carbon Light', but the problem remained. I was using the default theme and have reverted to this theme

Out of interest, If I install some of the other Firefox themes from the repository, can they be uninstaled, or, are they in place permanently?

Thanks

Is Plasmazilla a replacement for Firefox (uses same profile directories), or does it coexist with it?

What is Plasmazilla?

[TWPonKubuntu]

Plasmazilla is a plasma support library for Firefox and Thunderbird.

https://github.com/plasmazilla

It does not appear to have been updated recently. I don't use it, so I cannot advise, either way, on using it.
