|
When processing monitor config from guest store head0 width and height
|
|
for single-head configurations. Use these when creating the
|
|
DisplaySurface in the local renderer.
|
|
|
|
This fixes a rendering issue with wayland. Wayland rounds up the
|
|
framebuffer width and height to a multiple of 64, so with odd
|
|
resolutions (800x600 for example) the framebuffer is larger than the
|
|
actual screen. The monitor config has the actual screen size though.
|
|
|
|
This fixes guest display for anything using the local renderer
|
|
(non-spice UI, screendump monitor command).
