Summary	08961: all in n64/aleck64: fuzzy screen
Description	In all games in aleck64 picture is fuzzy when compared to previous versions with exception games that are using resolution higher than 320x237 This is probably conflict with initial resolution 3093x525 set for driver versus resolution switching in system 320x237. thus some strange upscalling/downscalling with filtering is enabled. Previous versions didn't have that problem. I have enabled integer only scalling with filter disabled in mame.

No.22432 Robbbert Senior Tester 9 days ago	If you ignore all that stuff about resolutions and filters and instead look closely at the screen, you'll see faint lines of garbage in the background. Aleck64 uses the N64 screen updater, so upon checking some games in N64, the same problem can be seen there too. There hasn't been much change this year - vas updated some memsets back in April, while holub added the COLD attribute to various functions more recently. I can only assume that one or both are responsible.
