Subj. In chromium issue tracker with screenshosts and other detail: https://bugs.chromium.org/p/chromium/issues/detail?id=543537 https://bugs.chromium.org/p/chromium/issues/detail?id=566147 Personally, I have i7-4500U. I think is Intel driver bug because on r600 all work good. Also all users who have this problem have Intel GPUs. DRM, xf86-video-intel from GIT with SNA and DRI3 enable. Kernel 4.4.1. I do not really imagine where to look to debug it. I think it breaks with the test depth when scaling the image. Thanks.
Added i915 platform = HSW i7-4500U = HSW
Same problem for xwayland + glamor from xorg-server 1.18.2

Also applies to IVB. Maybe it's not platform specific?

I don't think this is platform specific at all. I didn't try UXA, only SNA, but I can reproduce this on basically all Intel hardware I have (ILK, IVB and HSW for sure, haven't tested on my SKL and GMA950 laptops yet) if I enable GPU rasterisation on Chrome (chrome://flags/#enable-gpu-rasterization), regardless of the DRI version. Of course, one can argue that enabling an experimental flag is asking for trouble, but my GeForce 9400M (nouveau) doesn't complain.

Image rendering is very, very broken in Chrome running the latest i915 release. It seems to only occur when images need to be scaled (up or down). At 100% everything seems normal. A closer look at the issue (the images themselves) reveals that different image assets tend to be mixed together / overlayed and jumbled, even if these image assets are on other tabs!

Exactly the same behavior. I think the problem is somewhere in Mesa.

Do you still have problems when "GPU Rasterization" switched off in chrome:flags?
> Do you still have problems when "GPU Rasterization" switched off in > chrome:flags? No, of course. But then some sites terribly slow. This is not a solution. I'll try to find some CSS usually leads to such, this will narrow search problem.
>https://bugs.chromium.org/p/chromium/issues/detail?id=543537 Looks like it is finally fixed for me in Chromium 52.0.2743.24.
I don't know what the status of this bug is. I see that the first Chromium.org bug is Fixed and the second is marked as a duplicate. I'm going to close it, assuming it was not our bug. Please reopen if you believe there is still something wrong on our end.
