Canvas examples on MacOS don't work #342

andrewmh20 · 2020-05-13T03:39:35Z

0.1.1 seems to have broken the Canvas widget on Mac OS. When trying to run the clock, solar_system, bezier_tool examples on MacOS 10.14.6 get a blank, white, screen where I believe the Canvas is supposed to be. Running game_of_life presents a gray screen, and all the surrounding menu components but does not show any of the white "cell" pieces.

Manually switching to the 0.1 branch and testing the ones that exist there seems to work fine.

andrewmh20 · 2020-05-13T05:04:47Z

Realizing it’s possible I confused which code was which release/under development.
Is the current code in branch 0.1 the 0.1.1 release?
In that case, this is only a bug in the unreleased code on master, which can be expected-though still worth noting.

hecrj · 2020-05-13T05:53:46Z

I can't seem to reproduce the issue on macOS 10.15.3. The examples work as intended, even after a cargo update.

Is the current code in branch 0.1 the 0.1.1 release?

Yes, that's correct.

In that case, this is only a bug in the unreleased code on master

We upgraded wgpu in master (see #269), which I believe could be the cause of the issue. Unfortunately, it's going to be hard for me to debug it without being able to reproduce it.

Do all the wgpu examples work for you?
Do the iced examples work at b44f14e?

andrewmh20 · 2020-05-13T06:03:35Z

Do all the wgpu examples work for you?

~~Yes they do seem to work~~ I tested the wrong thing, standby...It still does in fact work (those examples in the 0.5 branch of wpgu)

Do the iced examples work at b44f14e?

No, they fail in the same way.

andrewmh20 · 2020-05-13T06:12:48Z

Okay I did some searching, 99e020c seems to break it

hecrj · 2020-05-13T06:17:33Z

What happens if you disable antialiasing?

https://github.com/hecrj/iced/blob/7565d294afd668cc95d85f15662d0704962c9614/examples/clock/src/main.rs#L9

andrewmh20 · 2020-05-13T06:19:51Z

That does it! With antialiasing off the clock works.

hecrj · 2020-05-13T06:23:05Z

Ok! Does the msaa-line example work for you? You can press left and right to change the MSAA factor.

andrewmh20 · 2020-05-13T06:27:58Z

Ahhh nope. It loads and I get a panic when I press left or right. Don't think I realized there was more to it than just getting the image to show up when I tested above.

Here's a backtrace:

andrewmh20 · 2020-05-13T06:31:28Z

Seems to be the related to this issue: gfx-rs/wgpu-rs#91

hecrj · 2020-05-13T06:32:08Z

The msaa-line example starts with a sample_count of 4, which is the same amount we are using in iced_wgpu when antialiasing is enabled.

If it works for you until you press left or right, then iced should work too.

andrewmh20 · 2020-05-13T06:40:16Z

Hmm yeah I see msaa-line starts at 4, but then whether I go to 2 or 8 it panics.


sample_count: 4

sample_count: 8

thread 'main' panicked at 'Attachment sample_count must be supported by physical device limits', <::std::macros::panic macros>:2:4

hecrj · 2020-05-13T06:58:41Z

Yes, that's more or less expected.

When you run game_of_life, do you see the background of the buttons?

andrewmh20 · 2020-05-13T07:03:17Z

I do not.

(and for the record, turning off antialiasing here also solves the problem)

hecrj · 2020-05-13T07:17:52Z

I do not.

You do, the buttons are there.

This is probably a bug in the blit msaa pipeline.

I double checked the shaders and the logic, and I am not sure what could exactly be causing it. I can't reproduce it. It works on my MacBook and my desktop with Linux and Windows.

andrewmh20 · 2020-05-13T09:13:21Z

Oh I thought you were referring to the little white squares.

Today is pretty much the first time I've looked at Rust, and the first time I've looked at this (awesome looking) library, so its likely this is either very wrong, or obvious: but I dug around a bit more to at least try to find where, and it seems like maybe it's related to the way these lines work? https://github.com/hecrj/iced/blob/d807ef367e0257ba54f8cf38708a7a61e28a4acb/wgpu/src/triangle.rs#L290-L358

When antialiasing is on, self.blit is not None so attachment and Some(resolve_target) are given to begin_render_pass, whereas things work if instead target and None are passed, as if antialiasing was off and self.blit==None

hecrj · 2020-05-14T15:39:34Z

Yes, that is expected.

When MSAA is enabled, in order to not overwrite the contents of the next frame, we need to resolve to a texture and blit it. I believe the blit part of the process somehow doesn't work in your system.

parasyte · 2020-05-18T01:59:16Z

FWIW, I have had similar reports with macOS 10.14.16 causing black screen in pixels, but I have been unable to track down the cause:

declanvk · 2020-06-25T05:37:02Z

I'm still getting the issues with the canvas when compiling from master (038f75e) when antialiasing is turned on. I confirmed that turning off shows the grid and other stuff.

Also on OSX 10.14.6.

Posting here because this seems like the same issue I'm having, but mine's even worse somehow.

When antialiasing is true, the clock and solar_system examples crash with this on the console:

-[MTLIOAccelRenderCommandEncoder bindEmulationArguments]:139: failed assertion `No render pipeline state bound'
Abort trap: 6

the OS crash log shows this backtrace: https://gist.github.com/JarrettBillingsley/7f67fbb15f62fe3dda087283aedb1e7b

Setting antialiasing to false avoids the crash.

I'm on a 2015 Macbook Air running mac OS 10.15.5 with intel HD graphics 6000.

@JarrettBillingsley It doesn't seem like the same issue.

Do the examples in wgpu-rs work for you? Specially the msaa-line one.
If you enable the glow and glow_canvas features, does the problem still occur?
