The red and green framebuffers were previously created only once at
the beginning of the test. If the test runs on multiple outputs with
different resolutions, the pre-created framebuffer's size might not
match the mode of a subsequent output, causing the modeset to fail.

This patch moves the framebuffer creation logic inside the
modeset_with_fb() function. This ensures that for every modeset
operation, a new framebuffer is created with dimensions that
perfectly match the current output's mode, preventing potential
modeset failures on systems with multiple displays of varying
resolutions.
