Bad mouse cursor rendering #336
Description
Some mouse cursors have a purple halo. This has been the case since version 1.7.1.4 (with or without "Force cursor shape"). Prior to this version, the halo was black.
The cursor on the left is the one normally displayed by the system, while the one on the right is the cursor as it is actually rendered.
>= 1.7.1.4 (tested with 1.7.1.4, 1.7.1.7 and 1.7.1.8)
Very visible with busy and working in background cursor:
< 1.7.1.4
Only the 3 Windows Default cursors have the problem; the others do not seem to be affected:
I once had the same problem with purple pixels with a client implementation, because it used the cursor-pixels sent by the server for the transparent pixels of the bitmask, but this data was initialized randomly. I have the impression that it's a bit the same thing here.
But the main problem seems to be an error in the mask since there is one pixel too many around the cursors.
