Correct link https://www.shadertoy.com/view/ld3Gz2 Seems to work fine with radeonsi FWIW. Is there anything interesting in Firefox's stderr output? Maybe the r600 driver is failing to compile a shader. This prints forever: EE /var/tmp/portage/media-libs/mesa-11.1.1/work/mesa-11.1.1/src/gallium/drivers/r600/r600_state_common.c:815 r600_shader_select - Failed to build shader variant (type=1) -1 EE /var/tmp/portage/media-libs/mesa-11.1.1/work/mesa-11.1.1/src/gallium/drivers/r600/r600_shader.c:161 r600_pipe_shader_create - translation from TGSI failed ! Same problem here, i see in logs -> also i saw that the hardcoded value for registers is 124, any reason for such small number? r600_shader.c:3662 r600_shader_from_tgsi - GPR limit exceeded - shader requires 230 registers Some new register allocation in TGSI landed in v17.3 and was later further improved. Could you recheck with version 17.3+ or, if that doesn't work, with the current git? On AMD 5450 and 6870 it works (the register limit is the same). -- GitLab Migration Automatic Message -- This bug has been migrated to freedesktop.org's GitLab instance and has been closed from further activity.
