Selur's Little Message Board

Okay, so if you feed 8k content into GLSL via vsplacebo it crashes and if you feed 4k content it works, correct?
(you resized to 4k and then applied the GLSL filter; here, there is no issue with 10k content; haven't tested further)
So this is probably some restriction based on the resolution, or some other setting in the drivers.
Did you change any of the default global 3d setting (or similar) for your card?

i resetted all nvidia driver settings. no change.

checked a bit more...
- using glsl saturation, gamma and rgbadjust ALL worked only after resizing to 50% resolution AND putting them at the end of the filter order.
- using those filters at "regular" 4k footage works always.

that's plain weird

After resizing, you are back to a 4k resolution, so that is not surprising if the limit is indeed 4k.
