Subject: [PATCH spice-common] canvas-base: Fix width computation for palette
|
|
|

images
|
|

|
|
|

Palette images are encoded with a slightly larger pixel than
|
|
|
18559f |
width. This cause a wrong calculation of stride_encoded value
|
|
|
18559f |
which cause a wrong stride adjustment.
|
|
|

|
|
|

This fix bug https://bugzilla.redhat.com/show_bug.cgi?id=1508847.
