Hi

Does anybody use darktable on a 4K display?

I have tried, and it crashes a lot.  Running it from a terminal just=20
gives the message "Killed".

The kernel log states that it is an out-of-memory situation.

It is not a very new computer. Its an Intel NUC with an i5 cpu with=20
integrated graphics, and 8Gb of ram.

I've tried to monitor ram usage using top while darktable is working,=20
but it never goes over 10% with lots of memory still available.

There must be some sudden spike in memory allocation that causes the=20
kernel to run out of memory, that I cannot see using top.

It almost certainly happens in the pixel pipeline, either when rendering=
=20
a photo for display, or during export.

If I switch the display to normal FHD 1920x1080 resolution, there are no=
=20
crashes.
