Installer pane is draggable inside the window

[Jeff Palmer]

I'm installing 15.04 on a 2013 Macbook Pro, 13" retina.

It looks like each 'screen' in the process is displayed in a pane or window, that you can drag around to relocate. One of the "panes" is titled "Install )as superuser) Preparing to Install Ubuntu' and the checkmarks for free space, plugged into power source, and connection to the internet are checked. Upong clicking 'continue' in this pane, I initially thought the installer hung. I waited for nearly 30 minutes, and it never progressed to the next screen. I tried movint that pane around with the mouse, as it seemed.. odd, like it was off center, and something was 'off the screen' below the visible area. However, the mouse was unable to move the 'pane'

Upon a second install attempt, before it got to this point again, I moved the pane to the top left corner, as far as I could. when I got to the same point mentioned above, I clicked continue. After a few moments, a UEFI warning popped up, telling me that some OS is set to bios compatibility mode. I suspect that it was actually this prompt that was below the visible screen real estate, and caused the assumed 'hang'.

After having relocated the menu, and accepting the UEFI warning, the installation proceeded. However, it also popped that same UEFI warning up approximately 4 additional times during the install process. This seems a bit excessive, as once should be enough. I'm not sure if the repeated prompting is intended, or a bug. But if it's intended, I would vote that it's a bit.. excessive.

I'll reinstall this evening after I get home, and attach some screenshots to this report, as I think that would do better than trying to explain what I mean by a 'pane"

After reading this again, I don't think I'm accurately describing the "pane"

I'm not referring to each screen during the install, but more.. the "frame" or "screen" that the install screen is being drawn onto. the window you can drag around with the mouse. maybe a better name would be.. modal?

[Jeff Palmer (je2f)]

This is after I drag the screen to the upper left. Notice how the underlying "pane" that the installation step is redrawn onto.. extends past the bottom of the screen you normally see displayed? I suspect the UEFI warning is being drawn "below" that, so if you don't drag it up.. the UEFI screen is never viewable.

For what it's worth, I installed this into a VM as well, and the installation screens look as you'd expect. So this appears to be isolated to this laptop, or display resolution in some way.
