Screenshot
This requires a tiny bit of preparation: have a full-screen
hardware-accelerated browser window in the background (Firefox, Chrome, both
are fine).
- Start Impress with OpenGL enabled, in a window.
- Run full-screen presentation.
=> After finishing the presentation, the background window becomes black.
See attached screenshot, I moved the LO window a bit to reveal some of the
browser window.
Bibisected to the following commit using repo bibisect-win32-6.3. I assume
something in the GL code relied on the previous, incorrect values from the
fixed functions.
