BeakerBrowser hangs when expanding its window on Trisquel 8.0

[JamesC1]

Test procedure:

• start Beaker.Browser-1.1.0.AppImage
• click and hold on bottom left corner
• push it toward the top right corner about half way
• pull it slowly toward where it started
• part way, the image changes from expanding to making lots of box edges

Extra verification steps:

• let go
• click the + for a new tab
• • new tab does not appear
• click and hold on the bottom right corner
• push it in a bit
• • new tab appears

I have used a command-line, and am open to doing some experimentation if it will help.
