Description of problem:
starting Chromium 79 (and also google-chrome-stable 79) through a ssh
tunnel gives a blank (white) window. Actually it is possible to click on
some buttons if one is able to locate them with the mouse without seeing
them.
By Clicking on "Chromium Web Browser" in the top bar of the screen, it
is possible to open a new window which is visible, but the window has
not loaded any personal configuration (bookmarks, extensions etc.)
Version-Release number of selected component (if applicable):
chromium-79.0.3945.79-1.fc31.x86_64
How reproducible: always
Steps to Reproduce:
1. ssh -X -f user@host "/usr/bin/chromium-browser"
2. a blank (white) window opens
3. click on "Chromium Web Browser" in the top bar of the screen and select
"Open a New Window"
4. a normal (visible) chromium window opens, but all personal configuration
(bookmarks, extensions etc.) is not loaded
Actual results:
a blank (white) window opens first, it is possible to open a second window but
without all personal configuration (bookmarks, extensions etc.)
Expected results:
a visible window is opened and all personal configuration is loaded.
Additional info:
chromium 78 works fine (as it has always done) over an ssh tunnel.

You might want to open a bug with chromium upstream here:
https://bugs.chromium.org/p/chromium/issues/list
The code diff between 78 and 79 is rather large, and I'm not sure where
to even start digging into what would cause X11 forwarding to break.

Workaround according to https://bugs.debian.org/cgi-
bin/bugreport.cgi?bug=949440
Bug seems to be related to MIT-SHM management
Works for me right now as follows:
- on the target machine install gcc and libX11-devel
- download XlibNoSHM.c from above link (at the bottom of the page)
- compile (always on target machine) with
gcc -shared -fPIC -o XlibNoSHM.so XlibNoSHM.c
- start chrome from the client on the target machine with
ssh -X -f user@target "LD_PRELOAD='libdl.so ./XlibNoSHM.so'
/usr/bin/google-chrome-stable"

The bug persists with google-chrome-stable-80.0.3987.87-1 , the above
workaround still works.

With google-chrome-stable-81.0.4044.129-1.x86_64 it is necessary to add
also the option --no-sandbox which makes it quite unsafe to use.

Just found another workaround, google-chrome-
stable-81.0.4044.129-1.x86_64 starts with
ssh -X -f user@target "LD_PRELOAD='libdl.so ./XlibNoSHM.so' /usr/bin
/google-chrome-stable --use-gl=swiftshader"
as far as I understand, swiftshader is a "high-performance CPU-based
implementation of the Vulkan and OpenGL ES graphics APIs, its goal is to
provide hardware independence for advanced 3D graphics ... act as drop-
in replacements for graphics drivers" (from GitHub) which could mean in
some cases worse graphic performances.
