Cant acces stash tabs

I do not know if its an already known issue or not.
I just cant acces my stash tabs. The problem is not always, its periodicly appears. For example i wanted to take out my unnatural instinct from the unique stash tab. I click on unique stash tab, that button works, but i cant switch between jewel, bow, sword or this sub windows.
I also wanted to buy some gear for my character, i was able to open the currency stash tab, but i was unable to take currency from it.

Any idea? no its not my mouse before you ask. when this bug comes mouse perfectly works for moving in the inventory only stash tabs are bugged somehow.
And it seems like the screen top 25% not working so whats on the top 25% the buttons are not working, but on the bottom 75% works. Very strange bug, do not really how it comes, than its just magicly dissapears all the time, but it always keeps up for 1-2 minutes. I will make a video, when it comes back, since i wrote this the bug gone.

but anyone having this problem?

So after testing around i found the source of the issue.
After a while i realised this problem is on the top side of the screen.
Turned out, if i have turned on discord overlay, than its listing the ppl names on the left side of the screen.
The list of names goes to top from botton.
More ppl in the room, the less works on the screen in stash tabs.
I turned off discord overlay and now everything works perfect!

i wrote this reply maybe gonna help for someone else too

im also suffering from this issue, except im not using discord or have any other apps open on the pc, i simply cannot interact with 2/3 of my stash currently, i cant select tabs, or take items out of the stash, i can put them in (using affinities only) but not take anything out. its been happening for a few days, idk what caused it but its pretty gamebreaking.. ggg plz tell me wtf is happening/how to fix it
