video wallpaper

Hi Well i just noticed, in the recent update for 11 t pro (xiaomi.eu_VILI_OS1.0.5.0.UKDMIXM_14), the video wallpaper get stuck once you open any app, and get back to normal when you lock the screen, this issue was not present in the xiaomi.eu_VILI_OS1.0.4.0.UKDMIXM_14 release, i was wondering...
