 This might be complicated, sorry Sluicebox.
 We've narrowed it down quite a bit already, and tested it on 2 diffent
 systems:
 1. Win 11, running Ubuntu jammy 22.04 via WSL 2 + XLaunch. ScummVM 2.7.0
 (Feb 18 2023 23:18:27) [my system, darkshoxx]
 2. Native Linux Mint 21.1 Cinnamon, 2.8.0git (Apr 5 2023 13:54:37)
 [someone else's system]

 In either case, running LibTas Version v1.4.4

 On my system it was tested in Gabriel knight 2, Shivers 1, Phantasmagoria
 1 and 2.
 On someone else's system it was tested on Gabriel Knight 1.

 The following occurs

 LibTAS booting the game, setting a safestate before playing a fullscreen
 video, , loading the savestate and then playing the video causes the game
 to freeze or crash. LibTAS itself will not crash. The error Message is
 along the lines of:

 X Error of failed request: GLXBadContext Major opcode of failed request:
 155 (GLX) Minor opcode of failed request: 183 (X_GLXIsDirect) Serial
 number of failed request: 181 Current serial number in output stream: 31

 Ignore the exact numbers, that's copy pasted from a different thread.

 What we HAVE figured out, is that it DOESN'T crash if the video is in
 half-video mode, such as is choosable in Phantasmagoria 1.

 To replicate:
 Install LibTAS v 1.4.4
 https://clementgallet.github.io/libTAS/
 run LibTAS, untick pause checkbox, add phantas 1 (or any of the other
 games) to game list, click until in main menu. press SHIFT+F1 to make a
 savestate. Press F1 to LOAD that same savestate. Click "Watch Intro".
 If the game is set to full-video it will crash. If it's set to half-video
 (accessible from the game options mid gameplay, not accessible from the
 main menu), it will not crash.
 If no savestate is made or loaded, it will not crash.
 If the savestate is made, but NOT loaded, it will NOT crash.

 Given that the crash also happen on Mint, I thought to rule out WSL,
 XLaunch, and specific Ubuntu version.
 We also tried Riven, which begins with a fullscene Cutscene, and it
 doesn't crash (wth savestates and all).
 So I was asssuming it is to do with the interaction between ScummVM SCI
 engine and LibTAS. But I don't know on which side the "discrepancy"
 happens. In fact I know nothing, I am just guessing, and providing you
 with as much info as I can.
 Like, there's a chance that this is a LibTAS bug, and has nothing to do
 with ScummVM. Just in case, I'll flag it as a bug here.

 If it's of any help, we went bughunting during this stream:
 https://www.twitch.tv/videos/1810457370
 and it happens pretty much right away.

 I currently don't know where the scummvm logs are on linux, If you let me
 know, I can attach them.
