The WMClass seems to have no authority when it comes to Chromium... I came up with this abomination (personal opinion... I'd just like for it to work with sh :) ) It has a few tricks, but is pretty robust for two windows.. The script sets individual classes for the opened chromium windows (not profiles, even though that is what I am after) You could specify further windows too, but they have to be manually added by adding more "specificprofile1"
along with the corresponding function.. Maybe someone could make it have more.. logic!
#!/bin/bash
# chromium-start.sh $1
# e.g. put:
# chrome-start.sh "Profile 1" to .desktop Exec=
# wmctrl -o 1366,0 ; chromium-browser %U --profile-directory=Profile\ 2 & sleep 3; wmctrl -o 0,0
# $1 = Profile folder name
profilename=$1
#2nd Chromium profile
specificprofile1="Profile 1"
echo "starting Chromium"
echo "args: " $1
echo "Profile name: " $profilename
echo "Specific profile: " $specificprofile1
# Just setting Chromium scaling variable, because of course Google Devs don't care about no fractional scaling on linux
scale_var=0.8
# Check if Chromium window with the specified class already exists
# Also allows using icons as "taskbar" switches (clicking icon takes to corresponding Chromium Window)
if wmctrl -l -x | grep "chromium-$profilename"
then
echo "Chromium Window exists, moving focus to it"
wmctrl -x -R chromium-"$profilename"
echo "true"
# Check if 2nd profile $specifiedprofile1 has been started yet or not. The WMCLASS(es) has to have been set correctly...
elif [[ "$specificprofile1" == "$profilename" ]] && [[ ! "`wmctrl -l -x | grep chromium-"$specificprofile1"`" ]]
then
# TODO: Nesting
if [ "$specificprofile1" == "$profilename" ]
then
echo $specificprofile1 "equals" $profilename

Issues:
Printing gives errors (deprecation warnings..):
Unescaped left brace in regex is deprecated, passed through in regex; marked by <-- HERE in m/%{ <-- HERE (.*?)}/ at /usr/bin/print line 528.
For debugging you can use the following to print out the errors when using actual icons:
https://askubuntu.com/a/664272/654028 (# The Manual alternative)
awk '/^Exec=/ {sub("^Exec=", ""); gsub(" ?%[cDdFfikmNnUuv]", ""); exit system($0)}' chrome-ws2.desktop
while loop bugs out, probably because of looping interval
Error: no such file "at while function"
xwininfo: error: -id requires argument
xprop: error: Invalid window id format: .
xwininfo: error: -id requires argument
xprop: error: Invalid window id format: .
xwininfo: error: -id requires argument
xprop: error: Invalid window id format: .
Also when clicking a corresponding .desktop icon too fast (before the custom class has been set ?), a new window will be opened..
(quite) Sometimes when starting from both Chromium too fast (~<3s), the class of the previously opened window gets reset to chromium-browser.chromium-browser..
Then you can expect the icons to have swapped around or other unexpected behavior.
