NM, I figured out the environment variable. And with the environment variable disabled, it renders properly!! Thank you for this workaround. This is much better than keeping a downgraded package. I configured my DE to run a script that sets this environment variable automatically when I open this program. Meanwhile, I'm so thankful for your help.
