You can create a rule on the Settings > Compatibility tab to disable the TitleBar Buttons just for LoL if you like, then you can leave them enabled for other applications.

Thanks! ]]> RE: Major Monitor Flickering while Running League of Legends under Windowed Fullscreen Mode https://www.displayfusion.com/Discussions/View/major-monitor-flickering-while-running-league-of-legends-under-windowed-fullscreen-mode/?ID=4382f942-45f0-4f90-bb92-70fd7f530db4#4 Fri, 17 Jan 2014 16:44:19 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/major-monitor-flickering-while-running-league-of-legends-under-windowed-fullscreen-mode/?ID=4382f942-45f0-4f90-bb92-70fd7f530db4#4 DisplayFusion Hey I just disabled title bar button and the flicker is gone!

So that's the reason why it's flickering, maybe displayfusion tries to apply the button and caused the flicker.

Are there any steps that I might be missing in order to make this issue occur?

Also, could you try disabling the DisplayFusion taskbar and TitleBar Buttons temporarily to see if that makes any difference?

I'll keep you posted on what I find out! ]]> Major Monitor Flickering while Running League of Legends under Windowed Fullscreen Mode https://www.displayfusion.com/Discussions/View/major-monitor-flickering-while-running-league-of-legends-under-windowed-fullscreen-mode/?ID=4382f942-45f0-4f90-bb92-70fd7f530db4 Tue, 14 Jan 2014 08:08:19 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/major-monitor-flickering-while-running-league-of-legends-under-windowed-fullscreen-mode/?ID=4382f942-45f0-4f90-bb92-70fd7f530db4 DisplayFusion So I bought Displayfusion a few days ago for livestreaming, and I found that League of Legends always flickers on my major monitor once the game starts loading under windowed fullscreen mode.
The weird part is that it doesn't flicker before the game starts loading, and it doesn't stop flickering until I change it into fullscreen mode.
Even more weird, once I set it into fullscreen mode, it stopped flickering; then I could switch back to windowed fullscreen and it works fine, no flickers whatsoever. But when I finished a game and starts another, it starts flickering again.

I've tested under various environment and hardware, the only way to solve it is to turn off displayfusion...

Is this a known bug or is it caused by some wrong settings on my end?

Here's my PC:
CPU: Intel Xeon 1230V2
HDD: 128G SSD
GPU: MSI GTX 660Ti / ASUS GTX 770 (tested both, both flickers)
Monitor 1: Acer P246H 1920x1080
Monitor 2: LG W2252TQ 1680x1050
