Under Android 9, toast messages (small, grey to black popups) would fade away quickly, maybe 5 or 6 seconds. Under Android 10 (On Pixel 2 XL) they are hanging around, sometimes until replaced by a newer popup or when screen contents totally change, other times seeming to age out after 5 minutes or so. In the meanwhile,, stuff at the bottom of the screen can be seen only through the transparency allowed by the toast message, which can make the phone pretty much unusable until it clears. Are other people experiencing this? Please let me know if I'm the only victim, I will try some sort of reset. Or, if you are experiencing it, does anyone know a technique for forcing the toast message to clear out?
