We currently don't have an option for this, but we do have it open as a feature request. I've added your vote to it, so we'll be sure to let you know if we have any information on it in the future.

Thanks! ]]> RE: Maximized Firefox on main monitor overflow on second monitor https://www.displayfusion.com/Discussions/View/maximized-firefox-on-main-monitor-overflow-on-second-monitor/?ID=f4467778-5253-43d7-aedb-98c70620915c#7 Tue, 23 Feb 2021 17:11:51 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/maximized-firefox-on-main-monitor-overflow-on-second-monitor/?ID=f4467778-5253-43d7-aedb-98c70620915c#7 DisplayFusion Hi Owen, if i disable windows transparency effects DF taskbar becomes opaque. But rest of windows is pretty ugly :'( Is there no way to ignore this setting for DF taskbar only ? Thank you. ]]> RE: Maximized Firefox on main monitor overflow on second monitor https://www.displayfusion.com/Discussions/View/maximized-firefox-on-main-monitor-overflow-on-second-monitor/?ID=f4467778-5253-43d7-aedb-98c70620915c#6 Tue, 23 Feb 2021 17:08:00 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/maximized-firefox-on-main-monitor-overflow-on-second-monitor/?ID=f4467778-5253-43d7-aedb-98c70620915c#6 DisplayFusion Hi David,

Ah, if you head into the Window Settings > Personalization > Colours> and disable "Transparency Effects", does the issue persist?

Ah, this is likely an issue with the browser. If you exit Display Fusion, does the issue persist?

I thought many apps were involved but I forgot I had Firefox opened almost everytime and as soon as it's maximized it shows on the second monitor whatever app is maximized/fullscreen above it on main monitor. Sorry I'll change the title in accordance. ]]> RE: Maximized Firefox on main monitor overflow on second monitor https://www.displayfusion.com/Discussions/View/maximized-firefox-on-main-monitor-overflow-on-second-monitor/?ID=f4467778-5253-43d7-aedb-98c70620915c#2 Thu, 18 Feb 2021 22:13:40 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/maximized-firefox-on-main-monitor-overflow-on-second-monitor/?ID=f4467778-5253-43d7-aedb-98c70620915c#2 DisplayFusion Hi David,

Is this happening with any applications in particular, or all applications?

Thanks! ]]> Maximized Firefox on main monitor overflow on second monitor https://www.displayfusion.com/Discussions/View/maximized-firefox-on-main-monitor-overflow-on-second-monitor/?ID=f4467778-5253-43d7-aedb-98c70620915c Thu, 18 Feb 2021 15:07:54 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/maximized-firefox-on-main-monitor-overflow-on-second-monitor/?ID=f4467778-5253-43d7-aedb-98c70620915c DisplayFusion Hi, as you can see my monitor setup is set as first screnshot. Problem is, when I go fullscreen on main monitor (#2) most apps extends on second monitor (#1) and are visible under multi monitor taskbar. See the grey bar at bottom of screenshot 2. Settings attached screenshot 3. Is there a way to prevent this overflow ? Or make DF taskbar really opaque ? Thanks !

**edit: problem occurs with Firefox only** ]]>
