Low framerate during Battle with a game RPG Maker 2003 in EasyRPG 3DS version

[Nolann59860]

Game Tested:
Donovan Adventure 2003: Final Mix, OFF, Nolann Horror Classic, Sample Game RPG Maker 2003 and most game made RPG Maker 2003

Player platform:
Nintendo 2DS, latest continuous build of the Player.

Describe the issue in detail and how to reproduce it:
When I'm in the overworld, the game runs at 60 FPS (it rarely drops to 30 FPS, but it's not a problem).
However, if I enter combat, the framerate drops to around 2-10 FPS in combat, unlike in the overworld.
I even tested it on a blank RPG Maker 2003 project; it runs at a maximum of 10-15 FPS in combat, while in the overworld it stays at 60 FPS.
Here are the screenshots taken with Luma3DS.

Had a similar issue with gameblabla@af1350f#diff-70f4d3beb86fa57bacd21ee7b20c2f34a01936d1f297c16f7b9790ebc7bc590e at 16bpp, when i discussed it with Ghabry. I was told it did not affect 32bpp but i guess i wrong. (?)

The problem is that the status window (that contains actors, hp, gauge etc) is refreshed every frame because changes can occur at any time due to event commands.

Guess the window could check if any of the rendered stats changed and skip the redraw in this case. (+maybe some fast path for "only redraw the gauge section")
