When using Apper to browse packages, if the information panel at the bottom is hidden and you click on a package, then you get visual corruption in the information panel that slides in from the bottom. This can be cleared by clicking on another window and then back on Apper or by clicking the "More" drop-down and selecting a different view. I've observed this behavior for several months now on two different machines, both running Arch Linux under KDE (with KWin). Since I think this is possibly a graphical bug, I will add that the first machine is using an AMD graphics card and I see the behavior with both the open source and proprietary drivers. The second machine is using an Nvidia graphics card and I have observed this behavior with the proprietary drivers. I have not tested it with the Nouveau driver. Reproducible: Always Steps to Reproduce: 1. Open Apper. 2. Navigate to any listing of packages (e.g., search for one or click "installed packages") 3. Click a package and expand the description panel at the bottom Actual Results: Description panel is corrupted. It looks like the expansion animation somehow freezes or sticks (it's hard to describe, see the picture). Expected Results: Description panel is free of visual corruption. The corruption can be cleared by clicking on another window and then back on Apper or by selecting a different information item. The glitch immediately reappears if you select a different package.

Please use oxygen style, working around this issue isn't cool
You're saying it's a bug with the Qt style, then?
I observe the same issue here with AMD radeon open source driver. In Apper and in Google Chrome.

I also notice that upon resume the mouse pointer is corrupted until the mouse is moved to a place where the pointer has to change.
