Unfortunately, this is a known issue that is caused by a new blank screen mechanism-specific features - the Monitor Driver was discontinued since the 126.96.36.199 Beta 2 version as it is outdated and soon won't be supported by Windows at all. Besides, the new screen blanking method is more versatile - namely, it works on laptops without blocking out the brightness controls (whereas the driver method has such a problem). Unfortunately, there are some downsides like the degraded colors when the blank remote screen feature is enabled. However, we'll do our best to improve the feature in our future updates. Sorry for the inconvenience.
