This is not only very costly, but also can produce glitches on the display/listener side. Instead, compare the current console size with the fitting console functions, which also works when the scanout is GL. Note: there might be still an unnecessary surface creation on calling qemu_console_resize() when the size is actually changing, but display backends currently rely on DisplaySurface details during dpy_gfx_switch() to handle various resize aspects. We would need more refactoring to handle resize without DisplaySurface, this is left for a future improvement.
