Boot logo badly formatted at start/stop of system

[Daniel LaSalle]

I have been having this problem since at least 20.04 but it definitely worked fine in a much more distant the past (such as 18.04 days and prior)

The problem is that when using a laptop plugged on a 65" TV (via HDMI) that the boot MATE logo seems to not be displayed at the very centre of the screenS. Instead it is moved heavily on the right-bottom side.

See enclosed picture.

Furthermore, when I unplug this HDMI cable and only boot the laptop then the MATE logo will actually be at the position that it is displayed on the 65" TV. That is not totally at the centre but also NOT in the corner, half hidden.

Regardless, on another system(regular PC+screen) the boot logo is normally displayed at the very centre of the screenS.

PS: This picture was taken using 21.10-latest

I think Plymouth tries to use the same resolution on all monitors. I'm not sure how that is chosen.

The attached photo looks like it's rendering a buffer that's higher resolution than either monitor and then can only display the top left portion. That will put anything at the centre of the buffer nearer to the bottom right of the screen.

Or it might just be a centring bug.
