Steps to reproduce the problem:
1.  on windows 10 1803 . Laptop hp-g005-ax with builtin display 1336x768 pixels and 1920×1080 monitor connected through HDMI
windows set to display on external display only (1920×1080);windows scaling set to 150%
2. open pdf (from netacad site with editable text fields) in chrome
3. pull out HDMI; windows sets resolution to 1336x768 and scaling to 125%

What is the expected behavior?

What went wrong?
pdf is still displayed correctly BUT when I hold& drag mouse or click mouse it selects/focuses text/fields located 200px below actual cursor position. Rightclick menu is also not under cursor..
The only way to fix is to reopen that pdf in new tab (this made me loose filled-in text-fields( )
