Bugs Bunny in Double Trouble (USA) Graphical issue

[Sandwich64]

It looks as though the background layer is intermittently resizing itself during gameplay for a single frame. This can be seen most frequently in the level Bully for Bugs which is accessible at the start of the game. Overclocking the CPU by any amount reduces the frequency of the problem.

Hmm... i remember fixing this issue a long time ago. It was caused by the game changing the screen width outside of vblank, which is not supported as the emulated frame buffer obviously need to have a fixed width for the whole frame. I fixed it by allowing the width to be changed up to a few lines after the start of active display (and rendering again those lines with the new width) so most likely it's again those late timing changes (to emulate 68k bus refresh or request delays) causing the width chznge to happen a little later and thus being not properly handled by the emulator :-/
