** Description changed: Start software-properties-gtk, switch to additional drivers tab. The program will start consuming 100% CPU for quite some time (many seconds or minutes depending on the machine). There is however no way to cancel the operation other than killing software-properties. Trying to close the window or clicking Close button hangs. Test plans ---------- 1. Start software-properties-gtk 1.1. Go to additional drivers tab. 1.2. Click close at the south-east corner or close the window via your window manager. Expected. Window closes immediately. 4. Start software-properties-gtk 4.1. Go to additional drivers tab and wait. Expected: The viewport will at the end say that either no drivers are available or show a list of drivers such as in the drivers-list.png attachment. The cancel and retry buttons are gone in the latter case. 2. Start software-properties-gtk and 'top' in a terminal 2.1. Go to additional drivers tab. Expected: The 'python3' command starts consuming 100% CPU. 2.2. Click cancel. Expected: The aforementioned process is no longer hogging the CPU, indicating that the driver scan really stopped. The retry button is clickable but cancel is not. 2.3. Click retry. Expected: The 'python3' command starts consuming 100% CPU. The retry button is not clickable but cancel ist. 3. Start software-properties-gtk and 'top' in a terminal 3.1. Go to additional drivers tab. 3.2.
