Hello to you all, I just added a third display to my laptop and have this unexpected behaviour. Whenever I hit Ctrl+space for autocompletion, the pop up shows on the wrong screen.
Here is initial setup: |DP Port n° 3| | Laptop screen n° 1 (main screen) | | HDMI Port N°2 | Display is extended to all screens. Netbeans runs on Screen 3 and any popup will show on screen 2. A fix consists in setting screen 3 as the main screen. This behaviour however tells us the display space is not properly propagated between OS / Java, but I haven't dug any further If someone needs further information / log, I'd be happy to help. This may be related to Murali Govind question. Best regards to all, Alain
