Subject: [PATCH] Fix scrolling on big endian platforms
|
|
|
|
The mask is defined as an array of 4*CARD8, but libxcb and Qt treat
|
|
it as array of CARD32, but that only works on little endian platforms.
|
|
|
|
Qt 6 switched to the array of 4*CARD8 representation, but that change is rather
|
|
complex for a backport but fortunately also not needed because 5.x only uses
|
|
32 bits. Use a little-endian CARD32 to have the same effect as 4*CARD8.
|
|
|
|
The diff is from https://github.com/void-linux/void-packages/pull/13901,
|
|
which is assumed to be the original source. Patch header and description
|
|
are from Fabian Vogt <fvogt@suse.de>.
