CLion freezes when trying to scroll a C++ source file

CLion always freezes when I try to scroll a C++ source up/down. As soon as the mouse hovers over scrollbar, the UI freezes.
Error logs on the console are like this:
2020-04-15 11:19:03,538 [ 170879] WARN - .diagnostic.PerformanceWatcher - UI was frozen for 24059ms, details saved to /var/fpwork/reiss/5g/.CLion/system/log/threadDumps-freeze-20200415-111844-CL-201.6668.126-MaskBlit.MaskBlit-24sec

Almost 30sec freeze is way too much and is really annoying. The only way to avoid this is to jump in the via "Goto-Line".

How can I upload the dumps file here???

EDIT: So below is an snippet of the dump files:
