Package: mypaint
Version: 2.0.1-10+b2
Severity: important
Dear Maintainer,
mypaint does not seem to work on (at least some) aarch64/arm64 systems. It
segfaults in PyObject after attempting to paint a stroke (i.e. just clicking in
the default canvas after startup crashes the program). My platform is MNT
Reform with Rockchip RK3588, but it was also reported crashing on NXP
i.MX8MPlus.
Here is a gdb full backtrace:
