RomM version
3.5.1

Describe the bug
I've tried loading three Flash SWF games using RomM, and all three have rendering issues when compared to Ruffle (both standalone player and the demo site).

To Reproduce
I loaded the following games (downloaded from Flashpoint):

• Bowman 2
• Boxhead: The Rooms
• PaintBall: The Game

Expected behavior
The RomM Ruffle player to render the games the same way the Ruffle player itself does it.

Screenshots

Bowman 2

The background seems to be transparent, making it difficult to view things. I tried using both light and dark UI settings in RomM, and in the browser, but it always uses a black background.

Boxhead: The Rooms

The menu loads just fine, but once the game starts there is just a blue screen (with some HUD elements). The controls and sound work, but unable to see anything.

PaintBall: The Game

Very minor, but the menu, game and text use painted lines, but the outline/shadow of these lines is missing in RomM.
