Browser hangs activating HTML select element

[AlexB]

Using chromium snap, whilst browsing a website, I sometimes experience a browser hang activating a HTML select element. I'm running Ubuntu 21.04 with the Ubuntu Unity package installed.

I have the following output when I start the browser via the command line.

ERROR: ld.so: object 'libgtk3-nocsd.so.0' from LD_PRELOAD cannot be preloaded (failed to map segment from shared object): ignored.
