Since I upgraded from Photoshop CC 2015 to CC2019 it has been a torture to work with Photoshop. Very laggy performance, polygonal lasso tool very slow when autoscroll to the left (even with Shift pressed). The properties tab doesn't close when clicking on "X" button, but it closes when you try to move the window.
The redraw is very slow, with several problems of visualization. For example, if I have 2 files open and I wanna flick from one file to another (Ctrl+Tab) my screen doesn't update and I need to undock it the from tab to redraw my screen.
Almost every time, if I'm working with my file docked in Tab mode, all the shortcuts stop to work and I need to undock in order to have the shortcuts working again.
In summary, its impossible to work healthy.

I've checked already and tried different settings on Preferences, but nothing has changed.
I've tried to remove Adobe CC products from my machine and reinstall from scratch, but nothing has changed.
All the drivers are updated to the latest version.

Hi Daniel,

Please go to the application folder C:\Program Files\Adobe\Adobe Photoshop CC 2019\Required\Plug-ins\Extensions\

And try renaming HalideBottlenecks.8bx by adding a '~' at the beginning of it.  Once you have ~HalideBottlenecks.8bx, restart Photoshop and let me know if that helps with general performance issues on your system.

If that doesn't help we'll move on to the next steps.

Hi gang, there's are performance fixes in the 20.0.2 update (released late last night) for the issue where removing the halide bottleneck plug-in and the sub-issue reported that painting lags and shows a skinny cursor each brush.

Let us know if you're still issues with the current 20.0.2 release. Thanks.
