Ever since upgrading to macOS High Sierra, I have been having trouble using QuickLook on .MDP (MediBang Paint) files. QuickLook will work fine previewing the first few files in finder before abruptly blanking on the rest (including files that were viewed before). It still works for all other filetypes though.
Restarting QuickLook using the above command in the Terminal fixes the problem for the next few files before the whole cycle happens again. MediBang creators claim it is a tablet issue.
Does anyone having experience with the tool have encountered it and was able to resolve? What are my options?
