PyCharm won't render correctly with 3d acceleration enabled in ubuntu guest

Created January 27, 2026 16:36

I upgraded Oracle VirtualBox on my Win 10 PC from 7.1.10 to 7.2.4 today (and upgraded Guest Additions to match). Sadly the display in the ubuntu 22.04 guest started flickering terribly - until I enabled 3d acceleration in the VBox settings for this guest. But then PyCharm 2025.3 won't render properly in the guest:

If I disable 3d acceleration PyCharm will render properly - but then the guest's screen starts flickering again! Note vscode displays no problem with 3d acceleration enabled. I've only seen this problem with PyCharm. Is there a fix for this with 3d acceleration enabled please?

Thank you! I can confirm that setting MUTTER_DEBUG_FORCE_EGL_STREAM=1 in /etc/environment in ubuntu, and then restarting the VM, fixed this for me!
