Hello

My system is Xcode 9.3, High Sierra 10.13.4.

I have an NSWindow containing only a subclass of NSOpenGLView. The view is displaying a simple texture. If I grab the corner of my window and start resizing, after a few seconds dragging the window edge around I get the following crash:

*** Assertion failure in -[MyOpenGLView _enableNeedsDisplayInRectNotifications], /BuildRoot/Library/Caches/com.apple.xbs/Sources/AppKit/AppKit-1561.40.112/AppKit.subproj/NSView.m:18293
[General] Overflowed needs display in rect posting count.

The crash always occurs. If I move the mouse more slowly, it takes a little more time to occur. Move the mouse faster and the crash happens sooner.

I post the full stack trace below. Note that at no point is any of my code listed in the stack. I do not call setNeedsDisplay or setNeedsDisplayInRect: anywhere in response to resizing the window. My gl reshape method is empty. There is no recursion happening in drawRect:.

I can workaround the issue by adding these empty overrides to my view:

- (void)_enableNeedsDisplayInRectNotifications
{ }

- (void)_disableNeedsDisplayInRectNotifications
{ }

It looks and smells like a bug in AppKit. But what is triggering it?

Thanks in advance

Could you post the code where you draw the content of window ?

rdevo,

Did you ever figure out any solution to your problem?

I'm having a similar issue, but mine is with a NSOutlineView.

I'm running MacOS High Sierra 10.13.6 and Xcode 10.1

I did find a workaround for my issue: If I change my outline view from "Regular" highlight to "Source List", the crash DOES NOT happen. However, with "Source List" as the highlighting type, the outline view changes to a darker background color with a blue highlight rather then my normal system highlight color. I then changed the outline view's background color back to the default control background color, and magically, the highlight color is back to my system highlight color and the source list outline view looks just like a "Regular" outline view — without any exceptions occuring when I resize the window!

I'll post the stack trace from the "Regular" NSOutlineView crash below, just in case it may shed some light on the underlying cause of the exceptions.

Could you post the code where the crash occurs ?

@mditsler I had a similar issue of my app crashing when resizing a view that contains a tableview.

Thanks to your story, I figured out my app at least will not crash when setting the table view highlight to "source list". If I change it to anything else than that, then my app will crash when the user resizes the window containing the view. Very frustrating.

This happened to me in Xcode 10.1 on High Sierra.

I will test later what happens when I convert this to Xcode 11.x on Catalina.
