Hi,

I'm suspecting it has something to do with the custom scaling factor of
windows... but maybe not. When setting it to a new value, you need to
logout and login again...

I did a screencast as you requested, you can see the bug happening after a
few launch (check the window height compared to the background window)

my version:= Version 57.0.2987.98 (64-bit)
Hope this helps,
Eric

I looked at you video again, and you did appear to set a custom scaling
factor. that is why the bug is not happening. I just re-tested it on my pc,
it *only* happen when setting a custom scaling factor.

open the location "Control Panel\Appearance and Personalization\Display"
and click on "set a custom scaling factor", enter "118%
 (make sure it is accepted), click apply, you will have to signout.. then
you will be able to reproduce the bug.

bsep@: Could you please take a look into this if its related to your change.

Note: Unable to repro on Mac by changing scale factor but was able to repro on Linux(Change in view is very minimal compared to Windows).

Of course it wouldn't reproduce before my change, we didn't support 118% scale factor before that...

I'll leave this open, but we don't really put any work into "unofficial" scale factors (those that don't appear in Settings>System>Display) unless it's a serious issue.

ok, thank you for your time on this.

 Issue 679014  has been merged into this issue.

This also reproduces at 125% per the duped issue.

This issue has been Available for over a year. If it's no longer important or seems unlikely to be fixed, please consider closing it out. If it is important, please re-triage the issue.
