So it seems the newer Picasso96 software creates an interrupt for the Spectrum card which requires acknowledge and will therefore not work with WHDLoad games which use this interrupt (e.g. kickemu games).

According to the changelog the interrupt has been added in release 1.36:
Changes in 1.36:
- This time PhotoGenics really does no longer open 2 color screens )
- Fixed p96CloseScreen bug which resulted in MungWall hits
- Fixed icon paint error in planar modes (BOBs with mask)
- Retina BLT Z3: remaining 24 bit panning problem fixed
- Changed the way layers.library handles Picasso96 PIP windows
- Spectrum and Piccolo boards now support interupts
- Reduced maximum polling time if waiting for a vertical retrace. This
will solve problems with DPMS on Cirrus GD542x based boards, which do
not generate display timings in certain blanking levels
- PicassoIV: merged API support for upcoming add-on modules
- Pixel64: fixed board driver setup (color palette routines)
There is nothing WHDLoad can do about.
Maybe there is option to unload the gfx card driver before WHDLoad and load it afterwards?

the problem should be solved in 18.6 where WHDLoad disables the p96 interrupts while installed program is running
