Description Béla Gyebrószki 2015-06-26 18:45:51 UTC

Some of my games when running in Wine crash on start, either immediately on startup like Skydrift, or during the initial loading screen.

Terminal output + Wine backtrace:
http://pastebin.com/TDsv0ZTh

The other game that crashes with an identical backtrace is named 'How to Survive', but no demo is available for this title.

The crash is present with the software renderer too (LIBGL_ALWAYS_SOFTWARE=1)
The problem doesn't occur with the binary Nvidia drivers (340.76), and reverting the following commit fixes the crash for me:

    main: _mesa_blit_framebuffer updates its arbitrary framebuffers.
    
    Previously, we used _mesa_update_state to update the currently bound
    framebuffers prior to performing a blit.  Now that _mesa_blit_framebuffer
    uses arbitrary framebuffers, _mesa_update_state is not specific enough.

To reproduce the problem in the demo version you need Wine (preferably the latest development version) and a Steam account. The game should run out-of-the-box after installation.

This patch reliably fixes the problem for me:

Please let me know if you need further logs.

Comment 1 Béla Gyebrószki 2015-06-26 19:08:11 UTC

The following patch by Ilia Mirkin also fixes the crash for me:

    /* We can use this to help debug user's problems.  Tell them to set
     * the MESA_INFO env variable before running their app.  Then the
     * first time each context is made current we'll print some useful

The 2 different patches equally fix the crash for me in those 2 games.

Comment 2 Béla Gyebrószki 2015-10-23 08:54:32 UTC

I can't reproduce this bug anymore: both games start properly with current mesa. Tried with wine 1.7.45 (the version available at the time when this bug report was opened) and with current wine 1.7.53: the bug doesn't occur in either version.

Marking fixed.
