Markdown Preview goes blank for tooltips
Answered
Markdown Previews initially render correctly but go blank whenever you mouse over IDE elements long enough for a tooltip to appear. The preview will render again when you resize the window or type in markdown file. This happens very consistently for every markdown files and even for the description section of Learn Courses. Nothing special appears in the error log.
I am using an M1 MacBook.

Does it help if you add ide.browser.jcef.gpu.disable=true in Help | Edit Custom Properties and restart the IDE?
The Custom Property didn't not fix it no.

I have the same bug. I'm 90% sure it's due to PyCharm being installed via snap on my system. This plugin probably requires Chromium, but maybe snap doesn't have PyCharm set to require it so it can't find it.

I don't quite understand the bug, but it does seem to be chromium related bug. If my limited understanding is correct, if you have multiple instances of Chromium running on your machine at once, if Chromium crashes it can leave a lock file that prevents Chromium from running new instances. Many programs use Chromium under the hood, so that's probably what happened.
