Incorrect canvas size in browser

[alexforencich]

I am seeing this issue when running the code in this repo verbatim with "trunk serve". Effectively, the UI does not appear to be rendering correctly in the browser, and I tested in both Firefox and Chromium. It looks like the UI "zooms in" immediately on load; it renders much too large for a fraction of a second and then disappears. Opening the developer console in Chrome doesn't show any useful log entries, but mousing over the canvas reports the canvas size as 22369600 x 22369600. Similarly, opening the developer console in Firefox reveals log entries about very large requested sizes. I also rolled the repo back to 0.29 and 0.28 and got the same result.

Firefox:

Chromium:

Some more results:

This page renders correctly: https://elliottslaughter.github.io/legion-prof-viewer/

However, building and running https://github.com/elliottslaughter/legion-prof-viewer locally results in a very strange result: it renders with the correct width, but much too short, and then the canvas grows vertically on every redraw, quickly extending off the bottom of the window. Seems like there is probably a change in some dependency that isn't totally locked down.

Does this https://emilk.github.io/eframe_template/ page render correctly for you?

For me it looks like

The logs are also fairly benign

Yes, it does render correctly on my end.

Here is the cargo.lock file for when I build eframe_template on my end:

Humm I opened the template repo in a github workspace and tried it in Brave and wasn't able to reproduce the problem. Are you able to reproduce it in a github codespace?

I only get somewhat expected errors in the console and it looks fine.
