Turning OFF Hardware acceleration fixes tons of bugs for me!

Ive had tons of bugs since 1.7 update both in Photo and Designer. Ive turned off Hardware acceleration because it actually slowed my machine and its also fixed a lot of graphical bugs with palettes and slow loading of files etc.

From the help file: 

• Hardware Acceleration—checking Enable Metal compute acceleration enables hardware acceleration on supported GPU devices (integrated Intel and any discrete graphics card, plus any external eGPUs connected via Thunderbolt 3 ports). Tools, adjustments, filters and other operations including RAW development will use GPU resources to achieve faster performance. The benefits are especially noticeable when stacking several Live Filter Layers together—export times are significantly quicker and canvas previewing is snappier. As a trade off, memory requirements are increased and performance may be dependent on the amount of VRAM available to the GPU devices. On systems with both integrated and discrete GPUs, both devices will be utilised for hardware acceleration. The make and type of all available GPUs will be reported directly under this option. Metal requires Sierra macOS (10.12.x) and above, with Affinity optimised for High Sierra (10.13.x) and above.

I've had it switched off since 1.6.X since i noticed a degradation in performance, rather than an improvement. Maybe because i've only 8GB or RAM in my machine. 

I switched hardware acceleration on (restart required, by the way) after i had read your other post about the swatches not behaving nicely. I didn't notice anything in that area myself but it maybe something the developers want to have a look at.

Ive got 32GB on RAM and 8GB VRAM but hardware acceleration makes the apps run slower (and causes quite a few bugs for me).
