How can I solve this?

I do not know the sollution, but I would advice in shortening your topic titles to make them easier to read : )

Example:

Thanks for this report… I filed it as RH-23380 for future reference. It looks like a bug with wallpaper and the render curves post effect. I’d use Neon here instead with either an image background in the display mode settings or a PictureFrame until this can be looked into.
