Subject: [PATCH] dix: set the device transformation matrix
|
|
|
|
The property handler is registered after setting the property, so
|
|
dev->transform remains as all-zeros. That causes pixman_f_transform_invert()
|
|
to fail (transformAbsolute()) and invert remains as garbage. In some cases,
|
|
this may then cause a cursor jump to 0,0.
|
