Summary: r200 falls back to software when clearing FBOs Product: Mesa Version: git Platform: Other OS/Version: All Status: NEW Severity: normal Priority: medium Component: Drivers/DRI/r200 AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: stefandoesinger@gmx.at
Created an attachment (id=50814) --> (https://bugs.freedesktop.org/attachment.cgi?id=50814) Sample application
glClear(GL_COLOR_BUFFER_BIT) causes a software fallback when a FBO is bound. The line in the debug output that signals this fallback is
r200Clear: swrast clear, mask: 100
0x100 is BUFFER_BIT_COLOR0 as far as I can see, which is indeed not handled in that function. I have attached a sample application that is a side product of attempting to reproduce bug 40552. The sample doesn't crash(yet), but it reproduces the software fallback.
