not able to choke my network as option isn't available in kernel module, connman or router. using iw to throttle bitrate seems to be unsupported by this intel chipset or at least it's not in the list of supported commands if you do 'iw list'.
flameshot 0.9 appimage took some digging to find but also crashes - wizard@wizard-fujitsu:~/temp$ ./Flameshot-0.9.0.x86_64.AppImage Run experimental self-contained bundle QSettings::value: Empty key passed QSettings::value: Empty key passed QSettings::setValue: Empty key passed QSettings::value: Empty key passed QSettings::setValue: Empty key passed Segmentation fault wizard@wizard-fujitsu:~/temp$ purged 0.9 and installed current flameshot 0.10.0.rc1-1 deb from github and it works as expected. then i purged 0.10 and reinstalled 0.9 from sid repo in case we need more testing. if i really need to run flameshot i can just disable checking for upgrades for the time being.
