[gwenview] [Bug 420141] Gwenview acts slow and leaks memory when zooming/panning images without an alpha channel when display color space conversion is enabled

I'm still having this problem. It's likely not seen by many people because most
people don't profile/calibrate their displays with a colorimeter, so don't have
display profiles installed (other than standard sRGB and the like).

My guess is that however Gwenview interacts with LCMS2 is probably to blame.

Hokay, I should have tried this before, but I think I know the culprit now.
This only happens when I UNcheck 'Apply only the profile embedded in the image
file'.

If I keep that option enabled, the slow-down never happens on any images. If I
disable it, images without an alpha channel slow down Gwenview and cause memory
to climb out of control. Images With an alpha channel are still fast and do not
cause memory usage increases.

I have both of my monitors profiled and calibrated, so having that option
unchecked allows me to see what images should look like on my monitor. At least
now I suppose I can choose between accuracy and speed, but I still don't
believe that memory should spiral out of control just by panning around an
image or changing which image is being looked at.

Unfortunately, I've noticed this behavior has returned. I don't know exactly
when, but currently I'm on Gwenview version 20.12.2.

At first I thought maybe it was because I used the Oibaf PPA to get bleeding
edge GPU drivers, so I just finished purging that repository to return to the
version of the Mesa drivers that come with Ubuntu's base packages. After
rebooting, the problem has still persisted.

Since upgrading to 20.04, this no longer occurs. Not 100% sure it's gone and
I've not extensively tested it, but I at least no longer have really horribly
sluggish behavior when looking at .jpg files.

What GPU driver do you have? Do you see sluggish behavior, or is it smooth?

I've gone ahead and tested it in Xephyr, and it seems smooth and without memory
leaks. However, this remained true when I added the '+igpu' and '-glamaor'
parameters to Xephyr. So it doesn't seem to be a GLAMOR bug, unlike the
slowness within TKGate (which persists within Xephyr with either of those
parameters).

mode; tested with JPEG images (these for sure don't have an alpha channel) with

I suggest to use a memory profiling tool, such as valgrind or heaptrack; leaks
might be caused by the video driver.
