In Sublime Merge (after using the computer for at least a few hours), clicking on “discard all” will suddenly freeze the monitor that is connected to the eGPU. However, the monitors not connected to the eGPU are fine. I need to unplug my eGPU and plug it back in.
This is often reproducible and seems to only happen in Sublime apps.
In Text, it seems to happen when I paste large contents into the window
MacBook Pro 2018 10.14.4
Sonnet Breakaway Box 650 with RX 580
Possibly the same type of issue seen with Display Link, here is details and something to try:
I have the same issues with version 3.2.1 build 3207 and a similar setup (Razor Core X and the RX580, a MBP 2017 with macOS 10.14.4).
Sublime Text crashes on almost any action taken when the window is on my external monitor. When I move the window to the MacBook’s own monitor first, it works without crashing.
After following the advice on the gpu_window_buffer settings, Sublime Text stopped crashing.
However, the version of Sublime Text I’m using has a workaround for the DisplayLink problem in its changelog already (which apparently doesn’t seem to help).
EDIT: If I read the last post in the linked thread correctly, the workaround detects usage of a DisplayLink adapter and sets this option automatically. That would certainly explain why the problem persists in this version.
Unfortunately 10.14.4 appears to be pretty buggy with NSOpenGLView. Setting gpu_window_buffer to false is your best bet for now if you are experiencing crashes.
