Subject: [PATCH] backends/x11: wacom pressure curve is a 32-bit property
|
|
|
e3f29c |
|
|
|
e3f29c |
The property has been 32 bits since around 2011 and has not changed, mutter
|
|
|
e3f29c |
expects it to be 8 bits. The mismatch causes change_property to never
|
|
|
e3f29c |
actually change the property.
