@sorokin.alexander.tver -- Thank You for the report.
Tested the issue on Latest Dev# 59.0.3067.6 on Windows 10, Version 1703 (OS Build 15063.13) and could not reproduce the issue.
Was able to open context menu and select all the options present in the menu. Enabled and Disabled Hardware acceleration but no luck in reproducing the issue.

Also navigated to the discussion forms and checked for any kind of similar issue, but could not reproduce it on Chrome.
Could you please upgrade your Chrome to Latest Dev and also provide us your OS Version and build details and if possible attach a screen cast of the issue, which would help us triaging the issue further.
Thank You.

I have the exact same issue.
Personally, I have AMD switchable laptop graphics - I believe they may be the issue; just like in the past. (Using Leshcatlab drivers, just so you know).

Same issue immediately after the Windows 10 Creators update on my laptop with an i7 m620, intel integrated graphics.

Javascript dialogs, allow flash dialogs and translate page dialogs are invisible unless hardware acceleration is disabled. 

Dialogs can actually be interacted with if you can guess the position of where the elements are.

Additionally Javascript dialogs block all brower interaction as the dialog takes focus and no browser interaction is possible until you press ESC to dismiss the invisible dialog.

Chrome version: 57.0.2987.133
Intel igfx version: 8.15.10.2900

Got the same issue with W10 Creators Update and i7-620m with integrated intel hd graphics.
Resetting chrome://flags doesn't solved the problem (only turning off hardware acceleration helps)

All Chromium based browser / All vesions
Intel driver version: 8.15.10.2993 or standart W10 driver 8.15.10.2900

I also have this issue. Driving me crazy!! Moved all work related shortcuts end stuff over to FF till this is usable again. If you want remote access so we can show you the issue Hand father any logs email me!!

I have same issue. No dialog box no translate. It kicks up end chimes at me cause I can't click the box. 
Any dev want remote access so we can show you the issue? Email me. 
I don't think it's a MS driver issue as my dell has switchable gfx end has to have dell supplied Intel end AMD drivers to function. Did not have issue before after creators but could have been chrome update around the same time.
