I have isolated the issue to items that have HTML in their description, e.g. if i go to the Intel ARK database and copy the entire white table with processor specifications (https://ark.intel.com/content/www/us/en/ark/products/80807/intel-core-i7-4790k-processor-8m-cache-up-to-4-40-ghz.html) to the description, this will reliably cause extreme lagging after switching view modes.
