Subject: 25.2; GTK3 scrollbar position does not respect scaling factor on
 HiDPI setting
Date: Tue, 27 Jun 2017 19:18:49 +0200

[Message part 1 (text/plain, inline)]

Please note that current configuration is built without toolkit scrollbars
since Emacs is unusable with them for me.

The toolkit scrollbars appear at 2 times the x-position they should with
gtk scaling factor=2 but at correct position with scaling factor=1, it is
apparent that it is not taken into account properly when calculating the
position.

Thanks!

This should be fixed on the current Emacs master now -- at least I'm
unable to reproduce the bug any more.  Can you check whether this works
for you too now?  If it doesn't, please reopen this bug report.
