Had a problem with a NVR not displaying cameras correctly in the web interface in Internet Explorer. The issue appears to be something wrong with how it is interacting with Windows scaling.
To resolve the issue you can set the scaling to 100%
If the monitor is a HDPI, set it to a 1920×1080 resolution with scaling at 100%.
Installing flash on Ubuntu is pretty straight forward. Type the following command into a terminal and press enter and away you go.
sudo apt-get install flashplugin-installer
On Fedora need to do the following
sudo yum install http://linuxdownload.adobe.com/adobe-release/adobe-release-x86_64-1.0-1.noarch.rpm -y
sudo yum install http://linuxdownload.adobe.com/adobe-release/adobe-release-i386-1.0-1.noarch.rpm -y
And install the Adobe Flash web browser plugin. The first command imports the GPG key for the Adobe Flash plugin repository and the second command installs the plugin itself.
sudo rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-adobe-linux
sudo yum install flash-plugin -y
