Hello I have a strange bug. 
Yesterday all was ok. But today I can't open image preview in google images. 
Each time the page opens anew in a new window.
Trying 3.5.3.39 64bit and 3.5.3.50 32bit
   

I understand the design to hide tabs if I open too many tabs, but the list even includes the tabs that are being displayed, which make the filtering quite difficult.

Thus, I wonder if there's any extension or option which makes the tabs work like a normal chromium browser?

Long story short: when you open browser whole window while opened for around 0.5-1 second display whole white light, which is flashing, and can provoke (already do) eyes strain. 

Please fix the problem.
Vivaldi browser, for example, did something to display grey instead of flashing white while opening their browser.
HW acceleration does not really affect the issue. Can be enabled/disabled and the issue will happen too.

So, what need to do?
1. Add extra an image or replace white color when opening a browser window to something more eyes friendly, for example, grey (modern bootstrap grey), or allow users to configure that part.

Hi, any ETA? Do you even work on it?

I don't know much, but it looks like security/privacy things. Mainly their push on SSL-only sites.
