Issues with f.lux when using multiple monitors
-
Hello, I've been using f.lux for a while now without any problems but I just got a second monitor and I've started experiencing a few issues, specifically related to the "disable for fullscreen apps" feature.
-
When I have the second monitor plugged in the "disable for fullscreen apps" feature doesn't seem to work at all for certain apps. However as soon as I unplug the monitor it starts working again. This mostly happens in games, even though I have them set to fullscreen/exclusive fullscreen.
-
For apps that do work, when I only have one monitor plugged in and I launch an app in fullscreen the transition to disabled happens slowly and smoothly over several seconds, but when I'm using multiple monitors the transition happens instantly. Is it possible to have the smooth transition even when using multiple monitors? The current behavior is a bit jarring.
Just wondering if anyone else with multiple monitors is experiencing these issues? Also this seems unlikely but my could the problem be coming from the monitor itself? My main monitor is an LG ultragear but my second monitor is a portable monitor from a relatively unknown brand.

@adityapstar is the second monitor plugged via just one USB-C cable? Sometimes these will use DisplayLink which puts f.lux into a different mode that is not always as capable. However, your "driver info" seems to say it should be working as a native device. If you have a spare HDMI cable, I might try that instead to see if it behaves better.
One second thing to try is to see if the second monitor can be disabled with the "Disable" menu, which makes a list of monitors. Since you said sometimes it does disable (without the fade) I would expect this to work, but I'm curious if it works with the games as well.
I suspect what's going on is we are not seeing these games as "fullscreen" which would be a bug we should fix - can you say which games show this?
