Help on rough jagged image texture on window mode.

As the title says, is there a way to fix this? From time to time I always encounter a visual novel that has this issue on window mode. Everything gets fix when I changed to full screen but I always play vn's on window mode. The last time I encounter this issue was on Magical Marriage Lunatics.

It was the goddamn original resolution of the game. It's 1600x900 while the max resolution available on the laptop is 1366x768. It seems there's no way to fix this unless I go hack the game and resize all the images to adapt to 720p resolution.
