pitcture display failure in LibreImpress

me flag

I am using ubuntu 20.04lts in a laptop with 20GB RAM. When the RAM usage is full around 15GB, the slides in LibreImpress can not display correctly. All the figures in slides can not been seen clearly (see https://imgur.com/eia3mrS https://imgur.com/DrrmlMV). How to solve this issue?

What is your GPU? It seems to me that your GPU can not handle the graphics. run `top` in terminal and check your graphic card's cpu usage. This gives you a better picture of what is the bottleneck.

GPU is NV117 / Mesa Intel® HD Graphics 530 (SKL GT2). I close all the running applications, because of not smooth system response. The information of running top is : top - 01:15:23 up 1 day, 9:20, 1 user, load average: 0.75, 1.72, 2.94. Tasks: 279 total, 1 running, 278 sleeping, 0 stopped, 0 zombie %Cpu(s): 10.8 us, 3.0 sy, 0.0 ni, 85.7 id, 0.5 wa, 0.0 hi, 0.1 si, 0.0 st MiB Mem : 19917.5 total, 7476.5 free, 4828.6 used, 7612.4 buff/cache MiB Swap: 15257.0 total, 15140.8 free, 116.2 used. 13976.0 avail Mem. So I need to reproduce phenomenon and run top again.

The max resolution that this GPU can handle is `4096x2304`. Maybe you are working with a higher resolution photos? https://www.intel.com/content/www/us/en/support/products/88345/graphics/graphics-for-6th-generation-intel-processors/intel-hd-graphics-530.html

The phenomenon appears again. 10GB RAM was used. The information of running top is : top - 00:42:00 up 11:44, 1 user, load average: 0.89, 1.22, 1.23 Tasks: 277 total, 1 running, 276 sleeping, 0 stopped, 0 zombie %Cpu(s): 4.7 us, 8.8 sy, 0.0 ni, 85.8 id, 0.7 wa, 0.0 hi, 0.0 si, 0.0 st MiB Mem : 19917.5 total, 269.2 free, 3587.8 used, 16060.5 buff/cache MiB Swap: 15257.0 total, 15217.8 free, 39.2 used. 10210.1 avail Mem. The vmware-vmx take %15.7 , soffice.bin 14.8% of GPU memory. vmwar-vmx always takes half of the cpu load, 53%. The display issue is strange.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
