While conducting a preplanned burn, during the burn itself, when opening the search list in the map view, and then clicking in the search text field causes the throttle slider to begin climbing up the edge of the search list until it disappears off the top of the screen. I have the following sliders active in order from left to right: Pitch, Slider 1, 2, 3, and Throttle. Only the throttle, which is lined up with the edge of the search list, has this issue, and it only happens during a planned burn. Clicking anywhere outside of the text field causes the slider to return to it's normal place at the top of the slider gauge. Clicking in the text field causes it to crawl up the screen again.
@Samps0n no, just the slider bar slowly crawled up the edge of the list until it disappeared off the top of the screen. Clicking away from the text field replaced the bar back at the top of the throttle gauge again, then clicking on the text field caused it to do the same thing again.
Unfortunately, I have not managed to replicate this since. I replicated it three times on that launch (using 'undo') but have not managed to get it to happen since. I uploaded that sandbox at the point that the issue was happening, but then when I reloaded it, I could not replicate it, so it may have been a one-off fluke.
