I am pretty sure that if you bring up EGL GBM platform and you miss a hardware driver, it will use llvmpipe and it will get stuff on screen (even if it has synchronization issues). I have had to patch Mutter to explicitly check for llvmpipe et al. and stop using EGL GBM in that case in favor of another path that does not suffer from the synchronization issues. Is there a significant difference between the automatic fallback to llvmpipe and using LIBGL_ALWAYS_SOFTWARE? Maybe one should use EGL_SOFTWARE=1 or such, does that still exist?</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
