SUMMARY Right and middle mouse clicks don't register sometimes. It's not a hardware error because they work in other applications. The problem appears on different machines too. STEPS TO REPRODUCE - Surf a little OBSERVED RESULT - Right and middle click won't work on some sites, but on others they do. EXPECTED RESULT - All buttons should work SOFTWARE/OS VERSIONS Linux: 4.19.11 KDE Plasma Version: 5.14.4 KDE Frameworks Version: 5.53.0 Qt Version: 5.12.0 ADDITIONAL INFORMATION It can't be reproduced reliably as it seems to fail randomly. Some sites will just not have working right and middle buttons sometime. The issue also started to appear recently I think, maybe triggered by Qt 5.12 upgrade. Enabling/disabling auto scroll and mouse gesture plugins had no effect.
I can confirm this bug. I also experience it. I can also direct you to second level. Enable mouse option "Scroll by dragging with middle button" and you will almost always need to use double click to open pages on new tab with middle button. It is rare to open link at new tab with this option enabled on first try, you need to use double click...
I think it started happening after the upgrade to Qt 5.12
I can't reproduce it, can you post some sites where it happened?
There is no pattern of sites where it happens, but it only seems to happen after a while of having Falkon open. So, a tab will start not registering right/middle clicks anymore, but when I restart Falkon, right/middle clicks in that tab work.
Ok, I can reproduce it now.
