Issue descriptionUserAgent: Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/52.0.2743.83 Safari/537.36 Vivaldi/1.3.551.13 Example URL: http://www.pouet.net Steps to reproduce the problem: 1. Having either an Intel HD integrated graphics chip or some specific Nvidia Geforce cards like the GTX 680 2. Smooth scrolling produces some screen tearing on Chromium 52 based browsers on pages with dark background if you open them, open a link on the same page, go back to the previous page and scroll around 3. Can be fixed if you turn off smooth scrolling What is the expected behavior? Disable smooth scrolling should not be removed because it removes glitches which appear thanks to the removal of GDI code which broke page rendering on certain graphics chips What went wrong? Removal of GDI rendering code seems to have screwed up rendering for various graphics chips (tearing) and introduced in general more blurry fonts Does it occur on multiple sites: Yes Is it a problem with a plugin? No Did this work before? Yes Chromium 51 and before Does this work in other browsers? Yes Chrome version: 52.0.2743.83 Channel: n/a OS Version: 6.3 Flash Version: Shockwave Flash 23.0 r0

Also, to see that it is a more general problem take a look to that threads, where the Steam client Chromium based browser part also got that tearing that is related to smooth scrolling: https://www.reddit.com/r/Steam/comments/4hzf45/is_there_any_way_to_disable_the_smooth_scrolling/ https://www.reddit.com/r/Steam/comments/4h74p7/valve_can_you_please_put_disable_smooth_scrolling/ or also in the Google product forums: https://productforums.google.com/forum/#!topic/chrome/X86KTB6z30Q So i hope Google either decides to keep that option in future versions (as it is not really a code bloat) or finds a way to make smooth scrolling more reliable without glitches.

Even more glitches in Chromium based browsers using version like 52.0.2743.117 or 52.0.2743.116 updates now even in hardware acceleration off mode - more than in teh updates before, even with deactivated smooth scrolling. What i forgot to post in the beginning: As i am not using hardare acceleration for glitches/tearing reasons this is what chrome://gpu shows. Graphics Feature Status Canvas: Software only, hardware acceleration unavailable Flash: Software only, hardware acceleration unavailable Flash Stage3D: Software only, hardware acceleration unavailable Flash Stage3D Baseline profile: Software only, hardware acceleration unavailable Compositing: Software only, hardware acceleration unavailable Multiple Raster Threads: Unavailable Native GpuMemoryBuffers: Software only. Hardware acceleration disabled Rasterization: Software only, hardware acceleration unavailable Video Decode: Software only, hardware acceleration unavailable Video Encode: Software only, hardware acceleration unavailable WebGL: Unavailable But that appearance of glitches now also in that fall-back mode which offers only software rendering since Chromium 52 (which was not the case in 51) perhaps it is not scrolling alone but a broken software rendering part in Chromium 52 and above?

Reporter: is the tearing still happening in recent chrome versions?

I don't see anything actionable here. |
