ccmake cuts off the end of log output

While running ccmake on a project with a lot of output (a top level Qt6 build in my case), I'm noticing lately that the end of that output is sometimes truncated. I may be losing up to 20 lines or so, maybe less. It is possible that the truncation only occurs when the configuration step succeeds but the generation step encounters an error. Perhaps there's a missed buffer flush before exit or something?

I'm on Linux using CMake 3.21.2
