Hey guys ..

I'm using ctrl+alt+arrow keys as shortcuts to switch between virtual desktops. Up until this morning (after package upgrade) everything was working fine.
Now I'm experiencig strange behaviour. Sometimes when I hold ctrl+alt and I press an arrow key, at first it switches to next desktop and on the next desktop I press arrow key again and shortcut does not work anymore until I release the ctrl+alt and press them again. It also happens that sometimes it's not working after I release the ctrl + alt keys and repress them ...
I did notice that if on second desktop I just switched to, (for example) where browser window is opened, the browser page started moving up and down as I press arrow keys as if It got focus somehow but ctrl+alt keys are not respected even though I'm still pressing them ....
At first I thought my keyboard died, changed it and I'm experiencing the same behaviour on another keyboard.
Anyone else experienced anything like that ?
I've checked if there are multiple shortcuts mapped for the same keys .. no duplicates found.
Kind regards

Armando
