Description
I can notice increased render time compared to 2.16.3, when moving my viewport around with 1-bit tif raster grid (with nodata transparency) layers enabled.
I thought it could be some kind of "debug" mode effects when released as 2.17-dev, but unfortunately 2.18 has the same effect.
I have only Skylake-U so it might be less noticeable in desktop CPU.
I now move back to 2.16.3 for quicker digitizing task.
Are there any changes in 2.17/2.18 that might cause this?
