I believe that at the moment bevy_egui doesn't work with bevy_webgl2 since it's not yet upgraded to 0.5. I'd like to hold off the release of 0.5 support until bevy_webgl2 is upgraded, but I'm fine with merging this to master earlier. So at least it'll be possible for users to point dependency resolution to this repo instead of the fork.

Alright, bevy_webgl2 shouldn't take too long to release, IIRC it is already ported to bevy main and just needs to be published.

Thanks for the egui upgrade! I'm going to test and merge this tomorrow :)

@jakobhellermann I believe there's a regression with users' textures rendering. See the ui example, now the Bevy logo isn't displayed (it should be in the left panel, like on the screenshot in the readme). I'm also not able to work on any Bevy 0.5 project after wgpu was upgraded to 0.7. I'm on Windows, here every project crashes for me on startup now: gfx-rs/wgpu#1317 :(

I can test things on my old Macbook, but it takes forever to compile... So I won't be able to help with debugging very actively.

Ok, now it doesn't crash but hangs. :)
(Now it's only bevy_egui, other Bevy examples work fine.)

The texture ui seems to have been broken by the egui 0.11 upgrade, I'll look into it.

I also noticed that sometimes minimizing an egui window will lead to a

wgpu error: Validation Error

Caused by:
    In a RenderPass
      note: encoder = `<CommandBuffer-(1, 114, Vulkan)>`
    In a set_scissor_rect command
    Invalid ScissorRect parameters

The ui is broken since emilk/egui@589bae1.

Removing the left to right layout in

I opened an issue: emilk/egui#289

The ui is broken since emilk/egui@589bae1.

Removing the left to right layout in

bevy_egui/examples/ui.rs

Line 64 in e5d083f

ui.with_layout(egui::Layout::left_to_right(), |ui| {

fixes the problem.

It seems like doing

ui.allocate_space(egui::Vec2::new(1.0, 100.0));
ui.horizontal(|ui| {
    load = ui.button("Load").clicked();
    invert = ui.button("Invert").clicked();
    remove = ui.button("Remove").clicked();
});

does the trick for us as well.

Looks great! Thanks again for your work on this

This is reproducible using

    egui::Window::new("Window")
        .scroll(true)
        .show(&egui_context.ctx, |ui| {
            ui.label("Windows can be moved by dragging them.");
            ui.label("They are automatically sized based on contents.");
            ui.label("You can turn on resizing and scrolling if you like.");
            ui.label("You would normally chose either panels OR windows.");
        });

Can I also suggest one change before releasing, add a egui_context.ctx() function and make the ctx field private. That way #13 can be done without a breaking change.

Yeah, I even hope we can merge #13 before the major release. :)

I've just stumbled upon this as well. I believe we should file an issue to egui about this. It sometimes returns negatives for clipping zone height.
