Issues with Chrome on Windows 7

We noticed today that the HTML5 tours don't seem to work that well in the latest version of Chrome (55), but only on Windows 7:





I appreciate that Windows 7 is fairly old and no longer fully supported, but since a sizable number of people still use it would be good to know if there's a fix for this issue without having to resort to using Flash.

Thanks,
Dan

Hi,

that's nothing new and not related to Windows 7 or any other specific system!

What you see is the buggy 'css3d software rendering' of Chrome.
It's there since the very first Chrome versions that were supported css3d.

It gets used when Chrome can't or doesn't want to use the graphics hardware for rendering css3d.
And that can happen on all systems - Windows, Mac and Android.

It might be that the latest Chrome update is blacklisting your GPU now and so Chrome is no longer using your graphics hardware for rendering.

The Chrome bug was reported already a several times for many years, but Google unfortunately don't want (or can't?) fix it, I don't know why...

Here some related Chrome bug reports - please post your opinions about that bug there:

Hi Klaus,

That's great to know - thanks for such an incredibly comprehensive reply!

It's a shame that this is happening, but at least with the information you've provided we can make sure we're aware of the issue.

Thanks again!
