3D babylonjs iframe rendering issues on Edge, works on Chrome/Brave/Firefox
Hey everyone, this link shows a demo of loading an iframe in the WebGL rendering engine Babylonjs. https://playground.babylonjs.com/#1DX9UE#186 This demo works on other Chromium browsers (and Firefox), but not Edge. Any idea why? <-- Firefox Edge -->Edge adds ClearType text rendering | Microsoft's own font rendering technology
Microsoft Edge Version 91.0.862.0 (Official build) canary (64-bit) comes with this new feature flag: Enhance text contrast Renders text using the same contrast and gamma settings that are used elsewhere in Windows. Run the ClearType Text Tuner to adjust the contrast and gamma settings for your monitor. – Windows #edge-enhance-text-contrast edge://flags/#edge-enhance-text-contrastBug: Selecting Text Causing Other Lines to Render as Random Characters (in Edge v81.0.403.1)
Since updating to Edge v81.0.403.1 (as well as KB4528760 and KB4532938 at the same time in my case), I (and several others) are often encountering a major text rendering issue where nearly whole lines of text end up completely scrambled with seemingly random symbols appearing in place of letters, with different random symbols occurring ever time re-rendering of the text is triggered. You can see the issue in the screenshot below of this page on Microsoft.com (for example, out of the dozens of sites it's occurred on). This issue occurs frequently (up to dozens of times per day), always after selecting text, but not ever time text is selected. This issue has occurred with dozens of different websites, and regardless of whether browsing in InPrivate mode with all extensions disabled. This issue only began occurring around 1/30/2020 after I updated to Edge Chromium Dev v81.0.403.1 (64-bit) and also installed KB4528760 and KB4532938 for Windows 10 Pro 1909 x64 (18363.592) at the same time, and I haven't encountered with any other browsers or Windows apps or UI. This often (but not always) affects nearly a whole line (after word-wrap) of text, often (but not always) in the paragraph following the one where text had been selected. Any action which causes the text to be rendered again – such as Alt-Tab (to a window on top of the browser) and back again, or selecting the affected text (to highlight it), or Win+Shift+S (causing screen to be tinted gray for screenshot selection), etc. – causes different random symbols to appear for the exact same portion of text that was affected. In some cases, deselecting all text will cause the rendering issues to temporarily cease, and in other cases, it just causes the random symbols to change to different random symbols instead. This is an intermittent issue. At times I can reproduce it dozens of times in a row, and other times I can go 20 minutes without being able to reproduce it even when trying intentionally to do so. Refreshing a page can cause this issue to go away temporarily. However, once it starts occurring it seems to occur more often for various pages or every time text is selected on a page. I also reported this issue with steps to reproduce via Send Feedback in Edge Dev, along with my email address. However, as I, unfortunately, have no way to reference that report here or reply to it or know it will be noticed (as can't flag as a bug or critical issue), I'm reporting it here as well. I'd appreciate it if this bug report could be passed along to the development team, especially as others have confirmed this issue here in this forums. I'm reporting the issue here with further details in case it may prove helpful, and also so that it may be easier for others encountering the same issue to find here so don't have to take the time to write up their own details reports regarding it. After, my initial report, I also found others, such as josh_bodner, jbart007 and Heath Bates, in this reply to the Edge v81.0.403.1 release announcement thread. My Configuration Edge Chromium Dev v81.0.403.1 (64-bit) Windows 10 Pro 1909 x64 (18363.592) KB4528760 and KB4532938 just installed at same time as the Edge Dev update For about:flags, I have Disabled #calculate-native-win-occlusion, #web-contents-occlusion and Enabled #edge-autoplay-user-setting-block-option, #dns-over-https, #quiet-notification-prompts. Multiple Edge Dev instances open with different profiles and 3 screens in use. NVIDIA GeForce GTX 1060 (Driver 441.66 installed 12/10/19) 32GB RAM Intel i9-9900K. Issues only began after updating Edge Dev and Windows, not any adjustment of flags, drivers or other configuration or browser usage changes. Additional Screenshots of the Issue As seen in these screenshots, this issue results in different random symbols showing each time re-rendering is triggered for text which occurs in close proximity to where different text had been selected. Sometimes different lines end up affected, sometimes the issue temporarily disappears after deselecting text, and sometimes different symbols appear for the exact same portion of text when triggering re-rendering or when changing what, if any, other text is selected.
Tabs not rendering (are blank pages) after desktop switch
I'm using Version 80.0.320.5 (Official build) dev (64-bit) on Windows Version 10.0.18362 Build 18362. My laptop is a Surface Pro 6. Both Chromium Edge and Windows are fully updated. If I am using multiple desktops with tabs open on one desktop and then switch to a different desktop to use a different app, then switch back, all of the tabs have 'empty' content i.e. the contents of the tabs are not rendered but leave an empty, white, background. They don't respond to clicks or scrolling and the only way to restore the browser to any functionality is to minimise and then maximise the browser window. This has been happening for several browser releases now so isn't specific to this build.Watercolor Effect rendering bug on New Microsoft Edge
This bug is ridiculous and funny at the same time. For some reasons, the whole Edge UI and the webpage, difuses pixels, gets blurry like if you dip your watercolor paint into water, that's what it looks like to me. Prolly some antialiasing bug on the GPU. My GPU btw is AMD 10-5750M APU with Radeon HD Graphics 2.50 GHz. This is still a good and fairly new laptop to me, a midrange Asus laptop from 2014. For some reasons, the only thing that's alright is the More options menu and all the context menu. The rest gets blurry. Here's a more detailed behavior description of the bug: If something is updating on the page, e.g. a circle loader, the whole UI will gets blurry fast, but when you just stay it still, leave Edge idle, it'll still gets blurry, but at much slower rate. After so much of blurring, it always gets back and rerender it again, and the output get's clear now, but it gets blurry again after some time. It's a loop behavior. And at it's very normal state, it never gets really clear enough, unlike the how clear the context or more options menu get's rendered. Here's a YouTube video detailing the bug in screen capture Please investigate this bug
