Ever since I've tried to fix the issue of DF taskbar being shown when there's a fullscreen like Youtube video on Chrome. I tried to Disable the option for "Show taskbar in front of full screen applications when they lose focus" and it did fix that, but the flickering has started ever since and no matter what I change I can't seem to fix it, it does go away for a while after reboot but it comes back.

Monitor setup (2 monitors, right monitor is primary, left monitor is secondary)
Monitor with DF taskbar (left monitor, secondary)
Monitor with Windows taskbar (right monitor, primary)

Taskbar that flickers is the DF taskbar on the left monitor.

@adaMATTium: The debug log shows that the RDP window is reporting itself as spanning all 3 monitors, so DF thinks it should force all of the taskbars to the bottom. Is the RDP window only on one monitor?


Weird. But, yeah, it's only on one monitor. These are also launched via RemoteApp if that has any impact. ]]> RE: Flickering taskbar on secondary monitor during games https://www.displayfusion.com/Discussions/View/flickering-taskbar-on-secondary-monitor-during-games/?ID=e19d26c9-6109-49b4-99d7-e90f611a39b3#36 Tue, 10 Oct 2023 21:11:45 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/flickering-taskbar-on-secondary-monitor-during-games/?ID=e19d26c9-6109-49b4-99d7-e90f611a39b3#36 DisplayFusion @adaMATTium: The debug log shows that the RDP window is reporting itself as spanning all 3 monitors, so DF thinks it should force all of the taskbars to the bottom.

I stumbled upon this issue myself. I ran into another post of yours to address an issue I have with RDP sessions, wherein the DF taskbar overlays the RDP, hiding the session's taskbar and such. I was able to address this by creating a compatibility rule that forces it to treat the mstsc.exe instances as a fullscreen application.

However, as a result of this, it is causing my taskbars to flicker, namely my monitor 1 with monitor 2 sometimes doing it. Strangely, it only happens when the RDP window is not minimized to the taskbar.

I attached the debug log, per your instructions. I recreated it a few times with the most recent being around 11:09 AM Central, today, 10/10/23. ]]> RE: Flickering taskbar on secondary monitor during games https://www.displayfusion.com/Discussions/View/flickering-taskbar-on-secondary-monitor-during-games/?ID=e19d26c9-6109-49b4-99d7-e90f611a39b3#34 Mon, 02 Oct 2023 13:40:56 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/flickering-taskbar-on-secondary-monitor-during-games/?ID=e19d26c9-6109-49b4-99d7-e90f611a39b3#34 DisplayFusion Sounds good, thanks for the update! ]]> RE: Flickering taskbar on secondary monitor during games https://www.displayfusion.com/Discussions/View/flickering-taskbar-on-secondary-monitor-during-games/?ID=e19d26c9-6109-49b4-99d7-e90f611a39b3#33 Sun, 01 Oct 2023 14:52:24 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/flickering-taskbar-on-secondary-monitor-during-games/?ID=e19d26c9-6109-49b4-99d7-e90f611a39b3#33 DisplayFusion Unfortunately, I haven't been able to reproduce the flickering.

Using the Steam 10.1.1 version of DisplayFusion.

While playing Dragon Age Origins in *windowed* mode, occasionally the taskbar on my second monitor flickers to display my desktop background behind it for half a second. The "Ignore Fullscreen Windows" fixes this flicker for *some* cases, like pressing `shift`, but just clicking the screen in general triggers it.

If it matters, I'm using Borderless Gaming release 9.5.6 to maximize the game window on my primary monitor. I'm running the game as administrator, with core affinity 1 and in Windows XP (SP3) compatibility mode.

I've never seen this flickering before on any other app or game on this PC, with or without Borderless Gaming, Flawless Widescreen, or any other overlay or window modifiying app. ]]> RE: Flickering taskbar on secondary monitor during games https://www.displayfusion.com/Discussions/View/flickering-taskbar-on-secondary-monitor-during-games/?ID=e19d26c9-6109-49b4-99d7-e90f611a39b3#30 Fri, 26 Feb 2021 18:35:03 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/flickering-taskbar-on-secondary-monitor-during-games/?ID=e19d26c9-6109-49b4-99d7-e90f611a39b3#30 DisplayFusion No worries!
