1. Bisected to r384374 "Turn on partial raster by default."
2. Using the older --enable-partial-raster bisected to r354966 that added this flag
3. Using the even older --enable-persistent-gpu-memory-buffer bisected to 
   https://chromium.googlesource.com/chromium/src/+log/8f939fa3..fc336926
   suspecting r350304 "WebKit" with the only CL inside:
   crrev.com/1356983003 "Set SelectionPaintingWithoutSelectionGaps to stable"

Disabling hardware accel doesn't help (Windows 7 and 10).
