Hi,
I'm using Krita 2.8.2 on arch linux. It's a new tool for me so my report may lack of precision.
The group of tool where there are crop, move and transform are (I don't know the name of the last one) doesn't work. I just can click on it. Even when my cursor is over the icon I've got no reaction unlike the usual thing : the square around the icon and the text description.
I've tried several thing without opengl, with opengl, with nvidia driver, with nouveau driver without success.
I've got also the docker overview who isn't working I've got just the title of the docker and the icons surrounding it.

Any help would be appreciated

There's a funny bug where if you stretch out the tools-docker too much, you indeed won't be able to select them. You might want to make sure the tools docker is only two icons wide.

It's a bug in QT(the underlying framework).

Thanks, it's solved my first issue ! The first thing i had done was to move around all the docker

I solved the second playing around with the size of the window of the overview docker while it's detached.
