I can't reproduce it with FF55 on Win 7. Could you provide a specific page to reproduce it, please.

I checked the page of AMD, I'm not sure your Radeon HD 6450 has drivers available for Win 10.

You can find my drivers here:

http://support.amd.com/en-us/download/desktop/legacy?product=legacy3&os=Windows+10+-+64

I'm using a Crimson Edition 16.2.1 Beta

Steps to reproduce: Open the Facebook for example, try to scroll and you will see.

One more strange thing is that I can't switch on H264 decoding, even if I forced all GPU settings, but officially AMD HD 6450 supports it.

Tried to install a fresh FF52 and caught the same bug on VK.com

Nightly 55 has the same problem with layers.enable-tiles on Radeon HD 6450 even with WebRender mode on.

Tiling is not supported on Windows to the best of my knowledge..

Correct - because it doesn't quite work correctly, and some of the examples are above.

I couldn't manage to reproduce this issue. Since the bug was logged 5 years ago, most likely isn't reproducible anymore for the reporter also.
Closing this bug as resolved: Worksforme.
