| Firefox fails to display shared tabs/windows | probable | high | Sometimes starting tab/window sharing before the call will not show the tab/window when someone joins conversation | This issue is tracked in Bug 1146882 and covered by regression testing |
| Shared window is displayed propperly | probable | high | There may be lots of windows that will not be propperly displayed | Periodical regression testing covers this area |

Summary
Context
Windows 10 and Windows 8.1 include an option to adjust the DPI (dots per inch) scaling in percentage for each monitor connected to the same PC. This gives you more control when you're using monitors of varying resolutions, rather than applying a single DPI scaling percentage to all of your monitors.
Enabling the feature
- Enabled by default in all Firefox 47 versions (Nightly, Developer Edition, Beta, Release) and available for Windows 8.1 and Windows 10.
- Can be 'disabled' if:
- Windows 8.1 - Windows's control panel choosing the option to "Let me choose one scaling level for all my displays"
- Windows 10 - match the size of text to all monitors connected to PC (Start > Settings > System > Display).
(note that 'disabling' this will affect all others programs as well since it's a windows setting)
