Not able to remove shadow from Chromium's menus

[fedxyz]

Hi,

I have problems with shadow effects on Chromium's menu, I am trying to exclude it from shadow.

On Chromium using xprop | grep -i class

returns me

WM_CLASS(STRING) = "chromium", "Chromium"

in picom.conf

I setup, under shadow-exclude section I tried (one of them at time)

"class_g = 'Chromium'"
"class_g ~= '^.*(C|c)hromium.*$'",
"class_g ~= '^(C|c)hromium$'",

and the same using "name".

No luck, I still have an horrible shadow effect on Chromium.

What am I doing wrong?

Thanks for the help.

Testing, the setting that work is:

   "name = ''",

that makes no sense...

Could be a bug. What version of picom are you using? Can you upload your trace log?

[fedxyz]

I am using picom v9 (9-1 from apt-show), I attach trace log file when the problem happen (I opened the popup menu in chromium), my config includes

   "class_g = 'Chromium'",
   "class_g ~= '^.*(C|c)hromium.*$'",
   "class_g ~= '^(C|c)hromium$'",
   "class_g *?= 'Chromium'",
   "class_g *?= 'Chrome'",

problem.log

Important thing that I didn't write before: it worked fine without any rule for Chromium in the config but after a Chromium update I have this problem.
