So i found this weird bug where factorios screen gets broken when you have most likely windows change the size of the screen temporarily.

For those who are wondering what the bug is. Look where my mouse is and what is selected. Its 100% misaligned.

So my setup:
I have 2 screens, 1x 1920x1080 (16:9), and 1x 1920x1200 (16:10)
On my 16:9 monitor i have a Fullscreen app running and on my 16:10 i have a Fullscreen windowed mode factorio instance open.

Sometimes this Fullscreen app switches around between Fullscreen and non Fullscreen and back.
For some reason that causes factorios screen to go to from 16:10 to 16:9 and then back to 16:10.
Not even sure if factorio picks that up but the screen is treated as 16:10 but the window is only 16:9..
Some real interesting desync happening here.

You should post a log.
When you say "Fullscreen windowed mode", what does that mean exactly? On the (confusingly cropped) screenshot I can see parts of desktop visible, which is the opposite of fullscreen.

Not that it is going to help since the log is not containing "debug infos" this just a waste of time.

@atomizer:
The window is actually in "Maximized" Mode. You know when button next to the "Close window button" that you click to maximize to the screen?
In other words how did i achieve that image with tiny bit of the desktop showing when the window is still in "maximized" mode?

This is the bug i am posting

Here are 2 videos showing the issue...
