Metal renderer invisibly disables seemingly at random
Thanks for filing an issue! Please answer the questions below so I can help you.
- iTerm2 version: Build 3.2.20180323-nightly
- OS version: 10.13.3 (17D102)
With the following settings
the metal renderer seems to disable for no apparent reason. I can verify this by using the FPS meter. The "Use Metal GPU-based renderer." setting stays enabled even though the FPS meter is not present. Toggling the "Use Metal GPU-based renderer." setting off then back on again usually fixes it.
I believe this started happening around the Mar 19 nightly—definitely in one of the recent nightlies.
