Bug#874054: Setting QT_LINUX_ACCESSIBILITY_ALWAYS_ON=1 has a huge negative performance impact, should not be always on
Package: at-spi2-core
Version: 2.24.1-2
Severity: important
According to [upstream] setting QT_LINUX_ACCESSIBILITY_ALWAYS_ON=1 has a
huge negative performace impact on Qt, so it should not be enabled by
default. And, if I understand correctly, this is the current behavior.
Upstream suggested that maybe we should try to only set this variable if
the appropriate hardware is found. Do you have any ideas on how we could
achieve this?
