memory leaks under wayland
Gimp, babl, gegl upstream, Linux
Description of the bug
Wayland compositor for GNOME causes lots of leaks in Gimp. Xorg works ok.
memory leak of VIRT, RES, SHR whilst calling gimp_polygon_select_tool_cursor_update
Memory is being leaked inside a gimp process. It includes virtual memory size. Which grows quite quickly. Don't know a tool to debug which call is increasing it so fast. As of actual reserved process memory. It's being leaked 1-2MiB per gimp_polygon_select_tool_cursor_update. Shared memory is also growing.
It's strange that massif tool of valgrind. It shows only 166MiB of heap memory being allocated. Whilst htop showed >1GiB of RES memory. And SHM wasn't that big as well to account for a difference between RES and heap memory (as of massif report).
Is the bug reproducible? Always
- Open up GIMP
- Create a new image with default parameters
- Move a mouse across canvas
- VIRT memory should grow about 100-200MiB per second
- Create a path with free select tool.
- Move a mouse across canvas
- RES memory should grow 20-100MiB per second
- SHR memory sometimes grows with almost the same speed as RES, sometimes much slower
- It allows to fill 7GiB of RAM with a consequent linux hangup
- After 300-700 MiB of memory leaked
- Switch to another window
- It usually crashes the application with a segfault inside some call to wayland compsitor
RES memory grows 1-2MiB per breakpoint hit inside gdb at the position below.
