i am running an Ubuntu 18.04.1 with all Packages up to Date. At the moment i have trouble Displaying some Programms such as gdit and calc.
In Gedit the background should be white, but it is somehow transparent and i am not able to use the Programm.
In Calculator seams to be a similiar problem somehow the inputfield is not rendered correctly.
I tried to find some solutions but dont know in wich direction i should look.
I gdm3 is spamming these messages in syslog but i dont know if they correlate with the problem.
