Issue descriptionUserAgent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3000.4 Safari/537.36 Example URL: https://jsfiddle.net/xl1blue/km7shxwz/ Steps to reproduce the problem: Open https://jsfiddle.net/xl1blue/km7shxwz/ What is the expected behavior? Firefox 52 https://gyazo.com/a47648d9b0387fd583b21439c3a206bf What went wrong? The background is split at the layer border and rendered incorrectly. https://gyazo.com/c87c54adbcd1be7fc95f2de653d956cb Does it occur on multiple sites: N/A Is it a problem with a plugin? N/A Did this work before? Yes Chrome 57? Does this work in other browsers? Yes Chrome version: 58.0.3000.4 Channel: dev OS Version: 10.0 Flash Version: I noticed this problem because my frequently used site was not displayed correctly today. But as I remember, the site is renderred correctly yesterday or 2 days ago. Bootstrap is using opacity + border-radius + background-clip for modal dialog. http://getbootstrap.com/javascript/#modals Perhaps some number of sites customizing Bootstrap are affected by this problem.

shiba200712@: Could you please review the attached screenshot and review the jsfiddle attached. Somehow I am not observing any difference with the jsfiddle attached above and comparing the same on reported(58.0.3000.4), canary(58.0.3004.0) and the latest stable(56.0.2924.87). Attached is the screen-shot of the same.

I found I had enabled --ignore-gpu-blacklist flag. (I am using Intel Iris Pro Graphics 5200) After turning the flag off, everything is rendered correctly. Sorry for lack of confirmation.

Tried a repro of this on Windows-10 on the reported version: 58.0.3000.4 with --ignore-gpu-blacklist flag enabled and I was still unable to reproduce the same. Tested on 'ANGLE (NVIDIA Quadro K600 Direct3D11 vs_5_0 ps_5_0)' and Intel(R) HD Graphics 4600 Direct3D11 using the latest canary(58.0.3004.0). India team doesn't have any windows system with 'Intel Iris Pro Graphics 5200', Looping MTV team for help in triaging this further if the same gpu is available.

Bug filer has indicated that this was only an issue because they had enabled --ignore-gpu-blacklist. Seems this is not actually a bug. |
