问题
Chrome 18 seems to have a pretty big problem with Ext 4 charts. Is there any way I can disable the hardware accelerated canvas? (I'm pretty sure that's what the bug is from) or will I have to wait for someone to release a patch?
回答1:
Command line switch: --disable-accelerated-2d-canvas
Added that at the end of my Chrome shortcut target and checked chrome://gpu/
Canvas: Software only. Hardware acceleration disabled.
