What device are you using?

Apple iPad Pro (4th gen 12,9”)

Description of issue:

I get this game crash several times when I start to play. Screen starts rapid flickering. GPU gets stalled waiting on an IOSurface (IOFence). Then I need to close app and reload it, after a while it starts running smoothly again. Started happening 6.2.2026 according to iOS log files

What were you doing before issue occurred:

Playing normally, it comes usually few times after starting to play after +6h break.

Screenshots or Videos:

Short video when it happened at menu screen

Time of occurrence

UTC+2 12:21:57 12.2.2026

Additional Information:

I can provide iOS made .ips file text of these crashes if needed (gpuEvent-TheWolf-2026-02-12-122157.ips). Logs indicate the app is the “guilty” part in all cases, not random hardware error.

Oh yeah… I probably should’ve mentioned that the iPad OS wasn’t fully updated, it’s iPadOS 26.1 instead of 26.3

# cursive marlin Maybe you should update it…?

That is… a solid plan. I don’t remember the exact reason but there was some network thing that requires some 5 minutes of extra efforts from me that has been the obstacle on that updating. It was claiming that something was preventing the update but which was blatant lie 😅but Apple being Apple or something. missing not one but two pretty important OS updates.

However, I remembered to take action now after checking from here…

…and it still does the blinking thing.

I haven’t played any other games than The Wolf, however someone else who plays “Static Shift Racing” with it has never had any issues. This is the only context it appears.

My iPad is likely the reason and especially if it’s unique with this bug. But it’s only making me reload the game or lock/unlock screen may work too, but t

The iPadOS own analytics files say:

"bug_type" : "284" ( I don’t know what Apple considers bug type 284 but this issue seem to have name?)

"restart_reason_desc": "blocked by IOFence"

In short it goes something like:

• Accelerator 0 was currently using IOSurface #16 (writing to it, direction=1)
• Accelerator 2 had 3 queued operations waiting on the same surface — all stuck waiting for Accelerator 0 to finish
• This created a GPU pipeline deadlock by because 0 never signaled completion within the given time window.

(By the way I’m really sorry for answer being so late. I have written that previous message some two days ago but never sent it, until now)
