I activate Borderless Window.
But when the Fullscreen Option is on i cant have another window in front of Minecraft while Minecraft are active...

The overlay then the other windows....

how fix that?

Please try the test build in #19, this should hopefully resolve your issue.

thx for that late Fix :)

What operating system are you using? What graphics drivers (Intel/NVIDIA/AMD/Hybrid) are you using? What overlay do you want to use?

I am aware of issues with overlays, but I can't look into any of them if I don't know what circumstances cause the issues.

My OS are Windows 10 exactly Build i need to seek.

I use a Nvidia GeForce 970 or similar (dont have exactly Model in Mind) (im not at home actually) It has 4gb Vram

I want as Example Youtube Video on picture in picture mode or Twitch to watch so that the stream is in the corner while i playing
