Critics argue that since Corel's acquisition, Paint Shop Pro has had few serious improvements, receiving only minor cosmetic changes, while demanding more system resources. The user interface has remained essentially the same since version 9 and long standing issues with CMYK editing and brush quality haven't been addressed. It's also argued that Paint Shop Pro is becoming too basic, focusing mainly on one-click photo fixes like "thinify", "Express lab" and "eye drops".
 Pricing policy
There have been criticisms of Corel's pricing policy that pitches international versions at significantly higher prices than those charged in the US. 
Another different (reversely) pricing example is the English version of Paint Shop Pro (release 9 to XI) could be more than 50% higher than that of a localized version. A Traditional Chinese localized version of Paint Shop Pro X was for sale at HK$699 in Hong Kong, whilst at the same time, the pure English "imported version" from the same distributor, having a price of HK$1199.
 Unreliability and instability
Version XI, in its launch version of 11.00, was criticized for the number of bugs and also for the 'Organizer' function's high CPU usage. Some of the issues were addressed in the patch to version 11.11 but the Organizer continued to attract criticism. It remains problematic when working with large picture collections. The 'Organizer' issue has been fixed in version 11.20.
 Spyware allegations
Versions XI and X2 install a third party program named PSIService.exe, listed under Windows services as ProtexisLicensing. Written by Protexis, this runs in the background and collects licensing information. This program communicates with a remote host and is described in some posts as spyware. The Corel EULA does not reveal that installation of Version XI or X2 will result in the installation and continued background execution of this non-Corel program. Uninstalling XI or X2 will not uninstall PSIService.exe; and upon manually disabling the Protexis Licensing service, Corel Paint Shop Pro Photo will cease functioning, stating "This copy of Paint Shop Pro has been damaged or illegally modified. Please reinstall from your original source."
 Limited color depth support
The latest version X2 has an incomplete implementation of 48-bit color. This color depth is limited to a handful of digital image correcting features, but not full-blown photo editing, where the real benefit can be realized. Updating to the latest version 12.01 will not provide full color depth support.
