megasync fix for deepin OS v20

fix.md

you can fix this by adding the env variable in the launch file:

nano /usr/share/applications/megasync.desktop

and then replace Exec=megasync with Exec=env QT_SCALE_FACTOR=1 megasync

remove the TryExec line and save. you can then copy the megasync.desktop launch file to your autostart folder, e.g.:

cp /usr/share/applications/megasync.desktop ~/.config/autostart/

if you don't want to vi/nano, you can use sed:

sudo sed -i -r '/^TryExec/d;s|^(Exec=).*$|\1env QT_SCALE_FACTOR=1 megasync|g' /usr/share/applications/megasync.desktop

and then copy the changed file to your autostart folder.
