Hmmmmm my guess is that the view of the issues VC doesn’t have a background set? Something has a black background and it’s bleeding through.

Also I tried to report this through the app but "report a bug" was broken. I assumed it would be fixed imminently, but if it's still broken I'll report it separately.

Already tracking, it’s from the org move

Closing b/c it looks like this is fixed on the latest TF build? I didn't do anything... 🤷‍♀️

[gingerbeardman]

I'm still seeing it

Version

@gingerbeardman which version of iOS?

11.3 (15E216)

It looks to me that the flashing is changing transparency of whatever is behind the overlap of the header.

[gingerbeardman]

Interestingly if I slide back when not replying (view moves horizontally) the flashing is less severe than if i swipe whilst replying (view moves diagonally, simultaneously horizontal and vertical)

So it's the content of this view that is being seen through the header as it fades between the two.

Can you walk through exact steps to repro?

Better yet if you could check out the project and help debug+fix that’d be great! I’ve got extremely limited time to spend on these edge cases.

Hmm ya doesn’t happen for me, gonna leave closed unless it resurfaced with more detail on what’s going on

Strange, now it's not doing it for me in this issue. I'll keep an eye out

[gingerbeardman]

OK. Here are new steps to reproduce:

1. Start GitHawk fresh
2. Tap a link that opens in a web view
3. Dismiss web view
4. Swipe screen slowly from left edge
5. Notice the flashing header

It does not happen unless a web view has been opened.

🤔 so the only blackish thing I can find in the view hierarchy is this UILayoutContainerView from the UISplitViewController.

[gingerbeardman]

I think the "something black" is a red herring?

[BasThomas]

It might be 🤷‍♂️

Ya those are the CALayers storing text bitmaps.

Thanks for the repro steps @gingerbeardman! I’ll take a look when I have time.

I’m able to repro this too.
