-windows 10 display scale will cause an exception
-Description of problem:
-windows dispaly sacle 150% or higher,  windows system will exception

-eg:
-dispaly sacle 150% ，mouse size will bu change to  57* 55  ，rgba data size = 12540,   we  need three QXLDataChunk

-
-this size [sizeof(QXLDataChunk) + 8118]  > second  QXLDataChunk's  alloc  size  , will  cause  qxl_get_check_slot_offset check fail
-
-
-for second QXLDataChunk, we actual alloc size  is (sizeof(QXLDataChunk) + 3876),  but we assign (8118 + sizeof(QXLDataChunk))  will cause an exception
