Windows Subsystem for Linux (WSL) Has Same Error
In Windows Subsystem for Linux (WSL) under Windows 10 there the file /usr/lib/i386-linux-gnu/mesa/libGL.so.1 does not exist. Instead there is the file /usr/lib/x86_64-linux-gnu/mesa/libGL.so.1 seems to replace it. However if you delete the replacement file the library doesn’t work at all.
Rename library then rename back solves problem
If you rename the file and then rename it back the errors disappear and it works a lot faster:

I verified the change is persistent, ie close the WSL terminal window and open a new window.
Quick Fix From Comments
In comment below it is suggested to try https://stackoverflow.com/a/63450299/6929343
export LIBGL_ALWAYS_INDIRECT=1
For a quick test, run:
glxinfo -B | grep renderer
NOTE: I haven’t tested this solution.
What’s Using the Library?
The library is used by yad in the lock-screen-timer bash script upgraded with hybrid support for WSL in addition to Ubuntu. Yad is a fork of Zenity which is why you see the Zenity-like Gtk-Message: reference in the third error message above.
Here’s what the yad window looks like in Ubuntu (in WSL it’s slightly different):
