"""A colour slider on Studio 1 turned red on release (app 0.2.55, firmware 0.2.47). An automation set a screen setting to the value it already had on every light change. The screen reported it, ESP Screen Manager saved the layout and resent the whole screen, and the screen drew its whole page again while a finger was on a slider. Touch input stalled, and the GT911's stray (0, 0) contact became the finger's last position, so LVGL moved the slider to its end on release. Each link is checked here.
