There is no issue with Telegram. They changed the framework to use a more Windows10 style for the Window frames. Regarding Pamac-tray, use mouse middle-click to open it. Else use the right mouse and the menu to access Pamac.
This is fixed with todays update:

Thanks, I fixed Telegram window.
Same problem.
@philm
can we also check this
https://git.kernel.org/pub/scm/linux/kernel/git/stable/stable-queue.git/diff/releases/5.7.7/efi-libstub-fix-path-separator-regression.patch?id=6392191d249cac00300106a39995b78ec5eb436f
( only in version kernel 5.7.7 actually )
there some topic that we can't restore Grub in EFI
Am I the only one that have a black icon for Pamac in Manjaro KDE when using the Breath2 theme? It is supposed to be white.
How you fixed telegram? Now it doesn't follow colours of other windows and buttons are on the opposite side of where they should be

Thank you! I just casually discovered that and I was coming to edit my message 
I even tried to download a package called telegram-qt but I'm not sure what it was, I'm so a newbie even after 5 years of Linux
You're welcome. Being a "newbie" is very relative, as all of us always have something to discover, learn and improve.
All good on first glance here on KDE/AMD
Due to the ongoing boottime issue / nsswitch.conf workaround i reverted my system to a working state with timeshift (10.6.2020) and updated from there - unfortunately the issue came back, so definitely not a configuration issue.
same problem here with pamac icon on breath2 theme
Hey @Frog and @eavy - There is a report on the pamac tray icon and i think was acknowledged
I'm sure will be addressed and fixed. Hopefully is not a big deal breaker for you 
Still having problems with the system tray on KDE Plasma.
1.) Pamac icon is still blurry
2) Pamac tray menu still has weird space
3) Telegram tray menu doesn't work anymore
-> on stable when I right click the Telegram icon, it opens a menu. On testing nothing happens but this small box looking like a graphical glitch appears:
All of these 3 are no problem on stable branch. I also tried switching the theme (tried with Materia, Breeze and Breath2) but it doesn't make any difference, tray is just broken on testing.
However, everything else is running fine and pretty stable
Edit: for problem 2 with the menu: It seems to be a problem with autostart. When I just log in and pamac tray auto started, it has this weird space. But when I kill it and restart it myself, the space is gone, just how it should be.
Also the problem with the telegram tray menu not coming up seems to have the same cause. I have Telegram in Autostart and if autostarted, the tray menu doesn't work. But when I start Telegram by hand some seconds after the session is started, the menu works.
So autostart triggers some tray bugs. Weird, doesn't happen with Plasma 5.18 on stable.
i updated today -- still same issue with ion pamac -- it is not a big deal it is just a cosmetic issue
all other things are working well
Does this update have Gnome 3.36.4? 3.36.4 has some major performance fixes.

Do you have re2 1:20200706-1 installed? Sounds like a partial upgrade happened somehow. Make sure your mirrors are up to date.
