 display (macos)

1. Use a dark theme (so that it's easier to see the incorrect background
color)

2. Start Emacs on internal laptop display, and observe fringe icons
(eg. new line indicators) are displayed correctly.

3. Drag the Emacs window to the external monitor, and observe the fringe
icons are all displayed on white background instead of theme color.

Hi, I can't replicate this. Can you please try building from current
master and checking if you still see this?

Hi I just rebuilt everything with latest master branch, and I can
still reproduce this problem.
It shows in all themes, including builtin themes.
I'm running on macos catalina 10.15.7.

Tested starting with "Emacs -q" then choose a builtin theme "wambat",
move the window to external display and I can still see the problem.

What are your screens like? Are either or both of them retina? If you
force a full redisplay by, say, resizing the frame, does the problem
remain?

My laptop screen is retina, but the external monitor is not.

Redisplay or resizing does not make the problem go away, icon
background remains white.

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

I tested emacs master on a retina display, and it is all good. fringe icons
are rendered correctly on both internal and external displays. However, on
low-res external displays the fringe icon rendering is still broken.

I've completely rewritten the fringe bitmap display on the master
branch. Can you please have a look and see if this is still a problem
for you?
