Description of problem:
Render of drop-down boxes not working well. After you change font (or make any actions with font selector) artifacts appears. The same with cell indicator, etc.
Version-Release number of selected component (if applicable):
Current version: libreoffice-calc-22.214.171.124-3.fc23.x86_64
But the same problem was with older version (lireoffice 4 on fedora 22)
Steps to Reproduce:
1. Open libreoffice calc
2. Jump between cells
3. Try to change font
This is a pretty obvious looking problem in your screenshot. But it doesn't happen here and its definitely a rare issue or there would be more reports of it.
So, there is something slightly unusual about your system or configuration in some way.
What is your desktop environment ?
This is just regular laptop without any customizations, regular kernel, no patches, etc.
Device: HP ProBook 470
OS: Fedora 23
Video: Intel HD Graphics 4600 (xorg-x11-drv-intel-2.99.917-16.20150729.fc23.x86_64 installed)
The screenshot looks like breeze icons. I suspect this is the same problem as bug 1291074
What's the output of rpm -q breeze-gtk ?
