Can you please confirm what fyne version (v2) you are using? The description says "1.4.3/v2" while 2.0.2 is the latest release.
You say that you are using an M1 Mac, but you are using Go 1.15 which has no support for that architecture. Could you please try with Go 1.16?

Virgil-N · 2021-04-23T06:34:35Z

I'll confirm later.

It's go1.16rc1 darwin/arm64

Jacalz · 2021-04-23T12:48:29Z

Thanks. Can you also verify the Fyne version, as mentioned in the comment above?

Can you please share the code that this is happening in? Might also be worth testing the latest Go release (Go 1.16.3).

andydotxyz · 2021-04-23T14:38:21Z

I have tested on the colo-M1 box (mac mini) we've been provided and it does not happen on that running a basic app.
I doubt that it is caused by your app code, but any more information you can provide will help.

Virgil-N · 2021-04-25T01:11:12Z

Thanks. Can you also verify the Fyne version, as mentioned in the comment above?

You are right. The Go version is 1.16 RC1. I'll install 1.16.3 and have a try.

Jacalz · 2021-04-25T07:13:18Z

@Virgil-N Did you find the source of the issue?

Virgil-N · 2021-04-25T13:02:50Z

@Virgil-N Did you find the source of the issue?

Not found.
I removed 1.16 rc1 and install 1.16.3 and the error disappear.

Jacalz · 2021-04-25T14:48:24Z

I'd count that as finding the source of the issue. Thanks for confirming.

Virgil-N · 2021-04-27T01:16:53Z

@Virgil-N Did you find the source of the issue?

Not found.
I removed 1.16 rc1 and install 1.16.3 and the error disappear.

I'm sorry. The crash is still here on Mac M1 with Go version 1.16.3.

And fyne version is 2.0.2.
I'll paste error information later.

Can confirm this is also happening on windows 10 with Go v1.16.3 and Fyne v2.0.3 (require fyne.io/fyne/v2 v2.0.3).
This is on a very simple test app with only two Entry fields and a button (login form) and no other logic.

Simply resizing the window quickly produces the crash.

andydotxyz · 2021-05-05T12:26:00Z

Are you on macOS Big Sur on an M1 processor as well @bloeys?

bloeys · 2021-05-05T12:27:37Z

@andydotxyz No this happened on Windows 10, Go v1.16.3 and Fyne v2.0.3

andydotxyz · 2021-07-30T22:42:44Z

@bloeys can you please post the crash log you see on Windows?

bloeys · 2021-07-31T14:57:37Z

Sorry I can't reproduce with my newer setup ( go1.16.6 windows/amd64).
Instead, now I get these logs when resizing quickly but no crashing or visible issues: PlatformError: WGL: Failed to make context current: The requested transformation operation is not supported.

Potentially the version fixed something, but I can't test now. Might have some time later to install and test with an older go version.

changkun · 2021-09-05T09:20:14Z

I believe this is a general issue with the upstream dependency glfw.

This is a simple reproducer that crashes not only on M1 macs but also on Windows (NVIDIA, 2080, driver version 471):

package main

import (
	"math/rand"
	"time"

	"fyne.io/fyne/v2"
	"fyne.io/fyne/v2/app"
	"fyne.io/fyne/v2/widget"
)

func main() {
	w := app.New().NewWindow("x")

	w.SetContent(widget.NewLabel("Hello Fyne!"))

	go func() {
		tk := time.NewTicker(time.Millisecond)
		for range tk.C {
			width := rand.Float32()*1000 + 1
			height := rand.Float32()*1000 + 1
			w.Resize(fyne.Size{Width: width, Height: height})
		}
	}()
	w.ShowAndRun()
}

The reason is, as explained in PR #2429, all draw calls are executed from a draw thread, but glfw itself works with the underlying frame buffer on a different thread. There are multiple race conditions:

glClear, glClearColor race with frame buffer resizing event
glDrawArray races with frame buffer resizing event
glfwSwapBuffer races with the above GL Calls

To entirely address the issue, if fyne does not remove glfw dependency, one must move all draw calls back to the mainthread instead of doing it in a different thread, and of course, there are drawbacks: draw calls may block event handling on the mainthread, and event handling can also block draw events. A solution might be using a command buffer to cache all draw commands and execute them as a batch on the mainthread, but apparently, it will be a significant change.

andydotxyz · 2021-09-06T08:16:16Z

We needed to move from drawing on the main thread to drawing on the draw thread so that applications could repaint during a resize operation (from when mouse makes first move to when mouse is released).
Doing this should not require race conditions as it is a recognised model for using GLFW - perhaps we need to move SwapBuffer or some other code executing on main thread.

Perhaps this should be revisited after the async-resize code lands? (#960)

andydotxyz · 2021-09-06T10:09:11Z

It would be good to test on latest develop now the resize code is improved.

andydotxyz · 2021-09-06T12:12:32Z

Sadly the async-resize does not seem to have fixed this but it has changed the stack.
No longer does it look like a clear GL race condition, the drawing is running on draw thread and main thread is waiting for it.

So I'm less sure why it happens now!

changkun · 2021-09-06T20:21:48Z

I still think the problem is a frame buffer race condition. The async-resize yet does not fix the driver frame buffer race.

As described in #2429, the race condition is:

ThreadMain. user drag the window -> mainthread receive resize event -> notify the change of frame buffer size (glfw side) -> GPU receives resize op
ThreadDraw. receive the resize event from mainthread -> resizes draw property -> conduct draw calls (fyne side) -> GPU receives draw op

The above GPU resize op and GPU draw op is racing on the frame buffer. If ThreadMain's resize op resizes the frame buffer to a smaller one, but the ThreadDraw's draw op is still drawing on a bigger frame buffer, it will lead to illegal memory access.

changkun · 2021-09-06T20:36:42Z

This is another evidence that the problem is from the upstream dependency glfw:

package main

import (
	"math/rand"
	"runtime"
	"time"

	"github.com/go-gl/glfw/v3.3/glfw"
)

func init() {
	runtime.LockOSThread()
}

func main() {
	err := glfw.Init()
	if err != nil {
		panic(err)
	}
	defer glfw.Terminate()

	window, err := glfw.CreateWindow(640, 480, "Testing", nil, nil)
	if err != nil {
		panic(err)
	}

	window.MakeContextCurrent()

	go func() {
		tk := time.NewTicker(time.Millisecond)
		for range tk.C {
			width := rand.Float32()*1000 + 1
			height := rand.Float32()*1000 + 1
			window.SetSize(int(width), int(height))
		}
	}()

	for !window.ShouldClose() {
		window.SwapBuffers()
		glfw.PollEvents()
	}
}

This program does not depend on fyne but still crashes (on Windows/NVIDIA exit status 0xc0000005).

Thanks for the clarity here, this is making sense.
Is the right approach going to be to fix in go-gl/glfw then?

changkun · 2021-09-07T10:01:05Z

Good question. But sadly I don't think it is going to be fixed as the problem is not yet being considered even from glfw/glfw side. See glfw/glfw#1682. An alternative solution to address the issue seems to need more investigation and experiments, such as gather draw calls in a draw command buffer, replace gl calls via modern driver (Metal, DX3D, etc).

I guess they think it is Win10 specific and not reproducible at this time.
Perhaps we can push them harder, or help them solve?

Downsize is resize is not as smooth, but upside does not crash. Fixes fyne-io#2188

There is a workaround in release branch now, so this can be considered resolved.
