Hi,

Open a file (anything it supports) in QtCreator.

Note that scrolling with your mouse scrollwheel works just fine as it should.

leave QtCreator open and suspend your pc.

Wake it up again. Now you can't scroll anymore.

This behavior happens in Linux (KDE) 100% of the time. I am kinda sure the same bug is on Windows too, but not 100% sure (don't have a windows pc to test at the moment).

My workaround for this is to close QtCreator after waking from suspend and re-opening it. It works again but is annoying.
