Hello there.

I'm receiving constant errors where if I have 2 monitors enabled it is causing my displays to flicker weird horizontal lines, usually gray in colour.

This seems to especially occur strongly during games that are borderless such as League of Legends and Witcher 3. I can regularly reproduce this error by just simply alt-tabbing. I have TitleBars disabled however it still occurs.

DisplayFusion was the last thing I'd blame it on as I've used it for years with no issue. However, after doing a lot of testing it seems to be indeed DisplayFusion. I've changed through multiple drivers, old and new and this still occurs. I've even done a fresh install and the monitors worked perfectly fine UNTIL I installed DisplayFusion on it.

I've attached a log file although I don't know how helpful it will be. I would love to get this fixed as I am a long time user and fan of DisplayFusion!

1. No
2. No
3. No

It's strange indeed. Like I said, it persists through multiple drivers and doesn't occur until I install DisplayDriver. These issues seem to be less prominent in version 6.0.

For further detail, these lines seem to start around the middle of the screen and persist downwards until it reaches the end.

Like This, but more severe. Happens randomly in-game or I can force it to occur if I alt tab.
