No
<span class="quote">> Do you think you could send me dumps with and without that optimization with the environment variable NIR_PRINT=true?</span >
I've attached the relevant parts of optimizations and the final NIR, the whole
dump is 300 mb so I didn't attach it.
Vulkan renderdoc of frame with issue:
<a href="https://mega.nz/#!sR8DGKwD!IHSQv6dWjk-YfyOnWZy36v-STBctmJbqGod19RPVDfg">https://mega.nz/#!sR8DGKwD!IHSQv6dWjk-YfyOnWZy36v-STBctmJbqGod19RPVDfg</a> .
Captured on Mesa master and HD 620. It is a capture of dx11 capture because the
app is 32 bit so I was unable to directly capture Vulkan trace of it. Don't
mind green artifacts in trace - they appear only in Vulkan trace.
The corruption starts from the call EID 2821, select "NaN/INF" overlay and look
at the only output of this draw. NaNs would be highlighted as red.</pre>
