Since I installed Lubuntu as my main OS (removed Windows which worked fine for years) I get random crashes. Sometimes before the crash I get visual artifacts (for example when moving a window) but most times it straight up crashes. This results in a black screen and the audio crashing on the way it loops the last second forever. The crash folder is empty. I have tried disabling my overclock and XMP and unpluging and plugging back the GPU cables but nothing helped. I also ran update and upgrade. The crashes sometimes continually happen at the loading screen but sometimes occur much later.
EDIT: This bug is not specific to Lubuntu as it is caused by the AMD dpm I have an AMD GPU and an intel CPU and am running Lubunu 19.04
