--- Comment #17 from Andrea Ippolito <andrea.i...@gmail.com> --- I can reproduce this somewhat consistently when I'm using IntelliJ IDEA: https://www.jetbrains.com/idea/download/download-thanks.html?platform=linux&code=IIC (just uncompress and run). IntelliJ IDEA's Wayland support is still experimental AFAIK, and since I'm using Wayland for my session I enabled the flag to let IDEA run natively on Wayland, i.e. once you open the app, Ctrl+Shift+A to open Actions search, then look for "Edit Custom VM Options...". In the text file paste: -Dawt.toolkit.name=WLToolkit Then restart the app. Now you're pretty much in my starting conditions. 1. clear the KDE clipboard history 2. In IDEA, open/create a scratch text file (e.g. Ctrl+Shift+A and type "scratch") and type two strings on separate lines 3. copy the first one, then copy the second one 4. go to a blank line on that same file, then bring up the clipboard popup (Meta + V here), and single click the second entry from the history, or highlight with the keyboard and press enter to select it 5. once the clipboard popup closes, try to Ctrl + V the selected entry Expected: entry is pasted Actual: nothing is pasted Mind you, this isn't reproducible if you follow these exact same steps but with just ONE entry in the clipboard history, so be careful. Also, these same steps don't trigger this bug in Kate, for example. BUT before reporting this to the IDEA folks, I wanna mention that once this bug IS triggered (from IDEA), you will also face the same issue in Kate. It's as if IDEA broke some communication pipe in an unrecoverable way. As I said in a previous comment, clearing the history temporarily resets things to normal.
