test program


Can you try with this test program and see if you can reproduce:

1. Save attachment as tfp-test.c

2. Build with 

  $ gcc -g tfp-test.c -o tfp-test $(pkg-config --cflags --libs epoxy xrender
xfixes xcomposite x11)

3. Run with 

  $ ./tfp-test

4. Use the mouse button to chaneg the Pixmap/texture or press a key to exit.

If you can reproduce then we may have a simple reproducer, that could be
helpful with the investigation.
