I double-checked the patch and also tried to build with --disable-opengl but couldn't find any issue. Can you please give me some hint? Like build errors you saw. What are changed by the patch are pretty much limited to virtio-gpu blob case and just one change in common area is egl_fb_blit function but the function interface stays same and there are no variables enabled only with certain define.
Is there any chance that the build system was building it with the previous patch, "ui/gtk-egl: un-tab and re-tab should destroy egl surface and context" still applied? Thanks!
