As per title, opening video is flickering. Doesn't happen with WineD3D. Can also be reproduced in trial version.

Uncapping frame rate by setting d3d9.presentInterval = 0 seemingly works around the issue.

Trial version can be found in Download section here, some mirrors might be dead by now, first one still seems to work.

For trial version to run:

• winetricks wmp9 to not crash on videos, will tell you It was not possible to complete Setup, which is fine

• if using gstreamer, lib32-gst-plugins-bad from AUR or equivalent to play the video (which is MPEG-1)

  the issues I ran into while trying installing lib32-gst-plugins-bad at the time

  • lib32-sord 0.16.8-1, lib32-sratom 0.6.8-1, lib32-lilv 0.24.12-1: ImportError: cannot import name 'autowaf' from 'tools', edit PKGBUILD and change touch __init__.py to touch tools/__init__.py in prepare()

  • lib32-openexr 3.0.5-1: imath errors, downgrade lib32-imath to 3.0.5 by editing PKGBUILD and changing version and hashsum

  • lib32-spirv-tools 2021.1-1: https://aur.archlinux.org/packages/lib32-spirv-tools#comment-815899

• (optional) winetricks fakejapanese to fix Japanese fonts

• set LANG=ja_JP.UTF8 TZ=Japan variables, game refuses to start otherwise

• run RewriteTE_Ver200/StartData/GameData/SiglusEngine.exe

To reproduce:

• start the prologue by clicking Start in main menu
• fast-forward through intro with Ctrl until video starts playing
• if game didn't exit cleanly during video playback, it will ask which backend to use (can also be configured from settings menu, ムービー設定 button), use WMP backend

Also might affect Summer Pockets, which runs the same engine, some ProtonDB reports seemingly report the same thing.
