1643895 - WebGL fails to show initial draw

Status: RESOLVED WORKSFORME

(Core :: Graphics: CanvasWebGL, defect)

Description

[d3ck0r]

Attachment: Left is what shouldn't be seen, right is what is expected.

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:75.0) Gecko/20100101 Firefox/75.0

Steps to reproduce:

I have this WASM test code I built a while ago...

https://d3x0r.org/javascript/wasmgui2/

Actual results:

only the background text of the page shows.

I have to resize the window, or open inspector tools, and mouse over the window with the select an item with mouse button enabled.

While capturing screen shots for this bug report (alt-prtscrn) I realize that tapping the alt-button causes the menu to draw and resize, and that also fixes the lost draw.

Expected results:

It should draw a semi-transparent window over the text on the webpage.

The website is only a couple scripts that you are free to download and use for testing without restriction.
