I'm using Affinity Photo 2, and I'm using the latest release of the app on my iPad, which is also running iPadOS 17.1.2. My iPad is an iPad Pro 11" with an M2 processor, with a storage size of 128GB.
I'm not sure what steps exactly make this issue occur, it seems to pop up completely randomly, on new documents or on old ones. It doesn't seem to matter if there's a large or small amount of layers, or whether or not I'm using the Apple Pencil. I try to open an adjustment menu for a filter (It doesn't seem to care what filter/adjustment it is, it happens on them all) and the menu closes itself constantly. It survives restarting the application, restarting my iPad, closing and re-opening project files, going to different project files, and seems to go away as randomly as it starts up. It just popped up again on a completely different project file of mine as well. The menu sometimes closes itself less than a second after it opens, and sometimes it closes while I'm adjusting things within said menu.
It has been happening since I was on iPadOS 16, and it's been happening on and off ever since Affinity V2.1. I don't know if it would happen on previous versions as I've had the program for less than a year.
I've attached a video of the problem happening, as well as one of the project files that it's popped up on.
