I'm using parallels toolbox for mac (3.9.1, os is macos 10.15.4, when i'm using macos 10.14, it works well). When i open parallels toolbox, the background of function icons is transparent, so i can't see the icons...... The screenshot is below.
My host is macbook pro, and Parallels Desktop which running inside it works well. The bug is about another software 'parallels toolbox'
Thanks, got it. Actually I thought that may be you are running macOS inside virtual machine and in this case some specific errors could appear.
Hello, which version of macOS do you use? Also, please generate Technical Report and post it's ID here: https://kb.parallels.com/en/124107 It will help to understand conditions for this issue.
Thanks for report ID. I see that you work on quite old MacBookPro (2011 year). It could be the reason of your issue - old video hardware that doesn't support some modern video effects. Anyway, I sent information about your issue to our engineering team. We will see what could be done here.
