I can confirm the sluggishness of 1.10.4 on a windows machine compared to 1.9.2. My machine runs with Windows 10, 32 Gig of RAM, an SSD and an Intel Core i7 notebook processor. I have updated the operating system and the graphics driver for the Intel UHD 620 chip to the latest one (according to the Intel driver and support assistant).
The sluggishness is most prominent when exporting Images with live filter layers, especially clarity to jpg. 1.10.4 would sit there for close to a minute befor the file is written, whereas 1.9.2. takes a few seconds to process the file. If there are no live filter layers, 1.10.4 is fast.
I downgraded to 1.9.2, 1.10.4 is simply a pain in the neck when exporting.
