* Screen.c: remove another pointless code blockUlrich Sibiller2020-10-171-10/+0
| | | | | Setting nxagentDefaultWindow[pScreen->myNum] is pointless because it is overwritten in the next code block...
* Screen.c: remove code that will have no effectUlrich Sibiller2020-10-171-5/+0
| | | | | | | setting a value for an attribute in the structure is pointless if you do not set the valuemask accordingly. Adding the missing valuemask code here would also be pointless because the valuemask is set to a fixed value later on. Therefore we can drop this code here.

| * randr: fix broken macros / memory corruptionUlrich Sibiller2020-10-161-3/+3
|/ | | | | | | | | | | | | By casting the rrScrPriv to ScreenPtr we are using the offsets from the Screen structure for referencing data in the rrScrPriv structure causing data corruption. As both macros use the same casting this still works until the location where the data resides is overwritten. For 64bit the location was the "rotations" member in rrScrPriv which was not problematic because it is barely used. But on 32bit it was "numCrtcs" which is heavily used. On unwrap this was 0 and lead to a segfault. Fixes ArcticaProject/nx-libs#943
