Operating System

No response

Steps to reproduce

I’m not sure if this is reproducible, so I’ll dump some additional information here.

I use nvidia with proprietary drivers (version 515.48.07) and contour built from commit 6d706d0. My WM is i3 without a compositor. Settings that seem render-relevant are set to default values.

The issue happens on terminal start.

Expected Behavior

contour starts with no errors.

Actual Behavior

contour shows the following error on start:

Additional notes

I’m not sure if this even a bug, since contour seems to work correctly after that, but I thought that behaviour is worth reporting.

Hey @GoldsteinE.

Thanks for the report. This is gladly not really an error but merely a warning from the graphics driver that cannot unroll a loop due to its high iteration count (16384), which may affect performance.

But you are right, it should not contain the text "error" if it is not considered one. I'd like to keep this information in some way to the log, but the severity should change and only be printed when requested as such.

After #1071
log for shaders can be asked via --debug gui.shader or will be included in --debug all
