[Qemu-devel] [Bug 1780815] [NEW] SDL Doesn't Rescale Image on Resolution Change

[Benjamin Hodgetts]

Public bug reported:

Whilst in fullscreen mode, if the guest changes resolution for whatever
reason, the screen doesn't update the scaling so you end up looking at
only part of the screen, e.g. if the guest changes from 640x480 to
1024x768, the image will still be fullscreen, but what you're actually
looking at will be the top-left most 640x480 segment of the screen
stretched out.

Manually going out of fullscreen mode and then back in fixes the
scaling, but you have to do that every time the guest changes
resolution.

QEmu 2.12.0 using qemu-system-x86_64 with Arch Linux host.
