copyCPUimage has null target error

[Dimatat0]

When I play episodes 5–8, this error causes the game to crash at random intervals. When this happens, the screen freezes, but the game continues to respond to clicks, judging by the voice lines. What can I do about this problem?

I suspect it is about OpenGL driver quality. Post what video card you have and which driver version for reference, though I will unlikely be able to tell much about the current state (I almost do not use Windows these days).

I guess you can try:

• Updating your GPU drivers.
• Making sure discrete GPU is used to run the game (if you have two GPUs).
• Switching between the renderers in settings (OpenGL ES ANGLE renderer might be more stable).
