2 problems : 1.new constrain proportion not working all the time 2.weird glitch on text

Hi,

maybe someone has this issue and can share a fix or a workaround.

so first issue is the new default constrain proportion. It works but not all the time. For some reason I have to press shift to constrain proportion.

example: I can resize a text or an image, it works, but when it comes to resize a smart object or a shape on the same document I have to use shift to modify it proportionally.... weird, maybe there is a hot key triggering this I don't know yet.

the second issue regards the text, since the cc 2019 update I have this really annoying behavior. when I select a text or move something on the canvas some texts have the top of the letters that disappear, like if there were a blank line running horizontally over it. Sometimes it returns normal after deselecting, sometimes not. So I have to make the layer invisible then visible again, or move the text up and down with the arrow keys to get it back to normal. Problem is that I've tried to save the images to see if it was a display issue but it shows up on the saved images, so I have to be extra careful when saving images, and having to move objects or make them visible/invisible several times while working is time consuming.

any clue ?

** UPDATE **

resetting the preferences corrected the smartobjects constrain but not the shapes/vector objects.

neither the text glitch 😕😕
